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.
