	  Single Kconfig option to select common base Cannonlake support.
	  This Kconfig will help to select majority of CNL SoC features.
	  Major difference that exist today between
	  SOC_INTEL_CANNONLAKE_ALTERNATE_HEADERS and SOC_INTEL_CANNONLAKE Kconfig
	  are in FSP Header Files. Hence this Kconfig might help to select
	  required SoC support FSP headers. Any future Intel SoC would
	  like to make use of CNL support might just select this Kconfig.
