This change will add support for serial training in
QPIC.
Due to different PNR and PCB delays, serial read data
can come with different delays to QPIC. At high frequency
operations Rx clock should be adjusted according to delays
so that Rx Data can be captured correctly. CLK_CNTR_INIT_VAL_VEC
in NAND_FLASH_SPI_CFG register is a 12-bit vector which is divided
in 4 parts of 3 bits each representing delay of 4 serial input data
lines. Bit [2:0] corresponds to qspi_miso[0], bit [5:3] corresponds
to qspi_miso[1], bit [8:6] corresponds to qspi_miso[2] and bit [11:9]
corresponds to qspi_miso[3]. Delay of each qspi_miso line can be set
from 0 to 7.
For serial training the following rule should be followd.
1) SW should write a page with any known pattern in flash at lower
frequency.
2) Set the CLK_CNTR_INIT_VAL_VEC for qspi_miso[0] line.
3) Read that page repetitively in high frequency mode until it
gets data accurately.
4) Repeat above steps for other qspi_miso lines.

This change will add condition check based on dts property
status ="okay" and status = "disabled" for qpic nand initialization.
qpic_nand init will get called if and only if the corresponding
dts file will set the status="okay" for nand-controoler node.
if status="disabled" then qpic nand initialization will be skipped.

Uboot passes the partition table in smem to kernel through
device tree. There is currently no method to specify
additional paritions to be created. This environment
variable addmtdparts allows users to specify new
partitions. The format is
setenv addmtdparts <newpart>[,<newpart>,...]
where <newpart> is <size>[@<offset>][<name>][ro][lk]
This syntax is same as in mtdparts part definition.
Example:
setenv addmtdparts 100M@0x8080000(diag)

To test minidump feature, we require a method to
collect full dump and minidump binaries on a
single run for side by side comparison.
This change enables dumping of minidump and
full dump binaries consecutively when uboot
env variable 'dump_minimal_and_full' is set.

This change will disable QPIC related clock because
all QPIC related clock setting is done by SBL.
If again we will try to access QPIC clock from u-boot
then due to xPU protection on QPIC clock register,
will generate the NOC error.
This change will also disable the global counter value
for clock source in register MPM2_MPM_CONTROL_CNTCR.
The global counter value setting is also done by SBL.
