This change is a workaround for Micron eMMC card. As per the card
extended CSD register value, the minimum size of a write protect
region is 0x8000 blocks (16MB). So the user should give start address
and size to align with 0x8000. But this eMMC part actually does
protect 32MB of memory.
We changing the minimum write protect region size from 0x8000 to
0x10000 for Micron eMMC card.

Starting part of device initialization sets the init_in_progress flag
only if the MMC card did not yet come to ready state and needs to continue
polling. If the card is SD or if the MMC card became ready quickly,
the flag is not set and (if using pre-initialization) the starting
phase will be re-executed from mmc_init function.
Set the init_in_progress flag in all non-error cases. Also, move flags
setting statements around so that the flags are not set in error paths.
Also, IN_PROGRESS return status becomes unnecessary, so get rid of it.

The polling loops in sd_send_op_cond and mmc_complete_op_cond functions
check the ready flag state at the end of the loop, that is after executing
a delay inside the loop, which, in case of exiting with no error,
is not needed. Also, one of these loops, as well as the loop
in mmc_send_status, have the delay just before exiting on timeout
conditions.
Restructure all these loops to check the respective conditions before making
a delay for the next loop pass, and to appropriately exit without the delay.

Some MMC cards come to ready state quite quickly, so that the respective
flag appears to be set in mmc_send_op_cond already. In this case trying

The previous change to use 'ocr' structure field for storing send_op_cond
command response also stopped using command response directly

The 'op_cond_response' field in mmc structure contains the response
from the last SEND_OP_COND MMC command while making iterational
polling of the card. Later it is copied to 'ocr' field, designed
to contain the OCR register value, which is actually the same
response from the same command. So, these fields have actually
the same data, just in different time periods. It's easier to use
the same 'ocr' field in both cases at once, without temporary using
of the 'op_cond_response' field.

Wider bus widths (larger than default 1 bit) appeared in MMC standard
version 4.0. So, for MMC cards of any earlier version trying to change
the bus width (including ext_csd comparison) does not make any sense.
It may work incorrectly and at least cause unnecessary timeouts.
So, just skip the entire bus width related activity for earlier versions.

If all the commands switching an MMC card to 4- or 8-bit bus width fail,
and the bus width for the controller and the driver is still set
to default 1 bit, there is no need to send one more command to switch
the card to 1-bit bus width. Also, if the card or host controller do not
support wider bus widths, there is no need to send a switch command at all.
However, if one of switch commands succeeds, but the subsequent ext_csd
fields comparison fails, the card should be switched to some other bus width
(next in the list for the loop), or to default 1-bit bus width as a last
resort. That's why it would be incorrect to just remove the 1-bit bus width
case from the list, it should still be processed in some cases.

This adds an API to do hardware partitioning on eMMC devices. The
new mmc_hwpart_config() function does the partitioning in one go.
As the different attributes and partitioning options on eMMC may
be interdependent validation has to be done based on the complete
partitioning configuration. The function accepts three modes:
- MMC_HWPART_CONF_CHECK: just validates that the configuration
is valid.
- MMC_HWPART_CONF_SET: validates and sets all the fields in
EXT_CSD but without setting the "partitioning completed" bit,
and thus is reversible.
- MMC_HWPART_CONF_COMPLETE: does everything and is thus not
reversible.

The mmc_startup() function uses the ext_csd data even if reading it
from the mmc device failed. This bug was introduced in commit
bc897b1d4d. We now bail out if

The eMMC spec says that partitioning is only effective after the
PARTITION_SETTING_COMPLETED is set in EXT_CSD (and a power cycle was done,
but that we cannot know). Thus the partition sizes and attributes should
be ignored when that bit is not set, otherwise the various capacities
are not coherent (e.g., the user data capacity will be that of the
unpartitioned device while partition sizes would be non-zero).
Prescence of non-zero partitioning data is nevertheless still used to
activate the high-capacity size definitions (EXT_CSD_ERASE_GROUP_DEF)
as it is necessary to set that to write any of the partitioning fields
in EXT_CSD, so having partitioning data means someone previously
activated that and we should keep it activated.

The eMMC spec mandates that the high-capacity group size definitions
should be enabled when the device is partitioned (by setting
ERASE_GROUP_DEF in EXT_CSD). The current test to determine when this is
required misses a few cases. In particular a device may have been
partitioned without setting the enhanced attribute on any partition
or partitioning may be completed without creating any extra partitions.
This change moves the code to set ERASE_GROUP_DEF to after reading
all partition information. It is also enabled when
PARTITIONING_SETTING_COMPLETED is set as it is necessary to enable
ERASE_GROUP_DEF before setting that bit, so it means that the user
previously switched to the high capacity definitions.

If the MMC_MODE_DDR_52MHz flag is set in card capabilities bitmask,
it is never cleared, even if switching to DDR mode fails, and if
the controller driver uses this flag to check the DDR mode, it can
take incorrect actions.
Also, DDR related checks in mmc_startup() incorrectly handle the case
when the host controller does not support some bus widths (e.g. can't
support 8 bits), since the host_caps is checked for DDR bit, but not
bus width bits.
This fix clearly separates using of card_caps bitmask, having there
the flags for the capabilities, that the card can support, and actual
operation mode, described outside of card_caps (i.e. bus_width and
ddr_mode fields in mmc structure). Separate host controller drivers
may need to be updated to use the actual flags. Respectively,
the capabilities checks in mmc_startup are made more correct and clear.
Also, some clean up is made with errors handling and code syntax layout.
