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.

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.

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(..).
