This commit converts UniPhier on-chip serial driver to driver model.
Since UniPhier SoCs do not have Device Tree support, some board files
should be added under arch/arm/cpu/armv7/uniphier/ph1-*/ directories.
(Device Tree support for UniPhier platform is still under way.)
Now the base address and master clock frequency are passed from
platform data, so CONFIG_SYS_UNIPHIER_SERIAL_BASE* and
CONFIG_SYS_UNIPHIER_UART_CLK should be removed.
Tested on UniPhier PH1-LD4 ref board.

This code doesn't follow the normal approach of having its arch-specific

To permit information to be passed from the early U-Boot code to
board_init_f() we cannot zero the global_data in board_init_f(). Instead
zero it in the start-up code.

Add driver model support to this driver, while retaining support for the
legacy system. Driver model GPIO support is enabled with CONFIG_DM_GPIO
as usual.
Since gpio_is_valid() no longer exists, we can use the -EINVAL error
returned from gpio_request().

Without the private libgcc, we need a full multilib toolchain with
different libgcc or multiple toolchains to build all BE/LE and
hard-float/soft-float variants of MIPS boards. That is not feasible.
This commit allows us to build all the MIPS boards with a single
kernel.org toolchain:
https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/
x86_64-gcc-4.9.0-nolibc_mips-linux.tar.xz
This change sounds reasonable for most users. If necessary,
you can disable this option via "make menuconfig" or friends.

The private libgcc is supported only on ARM, MIPS, PowerPC, SH, x86.
Those architectures should "select" HAVE_PRIVATE_LIBGCC and
CONFIG_USE_PRIVATE_LIBGCC should depend on it.
Currently, this option is enabled on Tegra boards and x86 architecture.
Move the definition from header files to Kconfig.

The motivation of this commit is to change CONFIG_USE_PRIVATE_LIBGCC
to a boolean macro so we can move it to Kconfig.
In the current implementation, there are two forms of syntax
for this macro:
- CONFIG_USE_PRIVATE_LIBGCC=y
- CONFIG_USE_PRIVATE_LIBGCC=path/to/private/libgcc
The latter is only used by x86 architecture.
With a little bit refactoring, it can be converted to the former.

This patch does the following:

- Remove unused defines
- Use clrsetbits() accessor functions
- Coding style cleanup
- Clear 25MHZ bit in timer controller register init for Armada XP
There is no functional change for kirkwood. At least not intentionally.
This will be used by the upcoming Armada XP support.
