f77dd6d7db ot1200: make use of imx_ddr_size(..)
To support different ddr3 memory sizes we should start using
imx_ddr_size(..) instead of the define PHYS_SDRAM_SIZE.

e37197acad ot1200: Fix error handling in board_mmc_init()
When an invalid USDHC port is passed we should return -EINVAL instead of 0.

Also, return the error immediately on fsl_esdhc_initialize() failure.

cb0b6986b0 ot1200: fix card detect for usdhc4
Today I got the final board and found out that a different
connector is used as the one on my development board. The
new connector has swaped pins for cd and wp.

This change is tested on a production ready board.

5a9ca420ce ot1200: add support for usdhc4
On the 'mr' variant switching to 'mmc dev 1' will result
in "MMC: no card present".

1199ddce9c ot1200: add feature pads
The older 'mr' variant and the generic variant of the
OT1200 differ in some places. As the name suggests the
generic variant supports more boot devices.

In order to be compatible with the 'mr' variant we define
some 'feature' GPIOs. On the 'mr' variant this pads are
not connected so we define their state with the help
of the internal pullups.

On the generic variant this GPIOs are connected and
represent the state of the hardware.

2e07c249a6 kconfig: arm: introduce symbol for ARM CPUs
This commit introduces a Kconfig symbol for each ARM CPU:
CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136,
CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100.
Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
for CPU_ARM1176 and CPU_V7.

For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.

Also, it removes redundant "string" type in some Kconfig files.

2e3a1f4d1d ot1200: fix sf detection
Commit 155fa9af95 changed the way
to define a GPIO line, which can be used to force CS high
across multiple transactions. In order to fix sf detection
change board code to make use of board_spi_cs_gpio(..).
