Kconfig: introduce writable boot device notion
Indicate to the build system that a platform provides support
for a writable boot device. The following will provide the
necessary support:
COMMON_CBFS_SPI_WRAPPER users
soc/intel/apollolake
soc/intel/baytrail
soc/intel/braswell
soc/intel/broadwell
soc/intel/skylake
The SPI_FLASH option is auto-selected if the platform provides
write supoprt for the boot device and SPI flash is the boot
device.
Other platforms may provide similar support, but they do that
in a device specific manner such as selecting SPI_FLASH
explicitly. This provides clearance against build failures
where chipsets don't provide SPI API implementations even
though the platform may use a SPI flash to boot.
