Add a "Platform Support" choice with four kconfig options: QEMU, RCAR3,
MPSOC and ALL_PLAT. They enable the required options for their hardware
platform. ALL_PLAT enables all available platforms and it's the default.
It doesn't automatically select any of the related drivers, otherwise
they cannot be disabled. ALL_PLAT is implemented by using hidden options
with default values depending on ALL_PLAT.
In the case of the MPSOC that has a platform file under
arch/arm/platforms/, build the file if MPSOC.
