This patch add DT support for mxc gpio driver.
There are one place using CONFIG_OF_CONTROL macro.
1. The U_BOOT_DEVICES and mxc_plat array are complied out. To DT,
platdata is alloced using calloc, so there is no need to use mxc_plat.
The following situations are tested, and all work fine:
1. with DM, without DT
2. with DM and DT
3. without DM
Since device tree has not been upstreamed, if want to test this patch.
The followings need to be done.
+ pieces of code does not gpio_request when using gpio_direction_xxx and
etc, need to request gpio.
+ move the gpio settings from board_early_init_f to board_init
+ define CONFIG_DM ,CONFIG_DM_GPIO and CONFIG_OF_CONTROL
+ Add device tree file and do related configuration in
`make ARCH=arm menuconfig`
These will be done in future patches by step.

Add a new entry in platdata structure and intialize
bank_index in mxc_plat array.
This new entry can avoid using `plat - mxc_plat` by using
`plat->bank_index`.

Make the driver model I2C API available always, even if driver model
is not enabled. This allows for a 'soft' switch-over, where drivers can
use the new structures in code which is compiled but not yet used. This
makes migration easier in some cases.
Fix up the existing drivers which define their own 'struct i2c_msg'.

This is necessary, as ppc4xx has the reset vector located at the end
of the U-Boot image. This needs to be flashed to the end of the NOR
flash. Adding the dtb to the main U-Boot image will break booting
on ppc4xx. This patch now embeds the dtb in the U-Boot image instead.

At present on some architectures we set up the following before calling
board_init_f():
- global_data
- stack
- early malloc memory
Adding the code to support early malloc and global data setup to every
arch's assembler start-up is a pain. Also this code is not actually
architecture-specific. We can use common code for all architectures and
with a bit of care we can write this code in C.
Add a new function to deal with this. It should be called after memory
is available, with a pointer to the top of the area that should be used
before relocation. The function will set things up and return the lowest
memory address that it allocated/used. That can then be set as the top
of the stack.
Note that on some archs this function will use the stack, so the stack
pointer should be set to same value as is pased to board_init_f_mem().
A margin of 128 bytes will be left for this stack, so that it is not
overwritten. This means that 64 bytes is wasted by this early call.
This is not strictly necessary on several more modern archs, so we could
remove this at the cost of some arch-dependent code.
With this function there is no-longer any need for the assembler code to
zero global_data or set up the early malloc pointers.

All callers of malloc should already do error checking, and may even be able
to continue without the alloc succeeding.
Moreover, common/malloc_simple.c is the only user of .rodata.str1.1 in
common/built-in.o when building the SPL, triggering this gcc bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54303
Causing .rodata to grow with e.g. 0xc21 bytes, nullifying all benefits of
using malloc_simple in the first place.
