soc/intel/{cnl,icl}: Move globalnvs.asl/nvs.h into common/block/
This patch creates a common instance of globalnvs.asl/nvs.h inside intel common
code (soc/intel/common/block/) and ask cnl & icl soc code to refer globalnvs.asl
and nvs.h from common code block.
TEST=Able to build and boot Hatch and ICL DE system. Dump DSDT.asl to verify
GNVS operation region presence after booting to OS.
