soc/intel/{cnl,icl,tgl}: Move northbridge.asl into common/block/acpi
This patch creates a common instance of northbridge.asl inside intel common
code (soc/intel/common/block/acpi/acpi) and changes cnl,icl & tgl soc code to
refer northbridge.asl from common code block.
TEST=Able to build and boot Hatch and ICL DE system. Dump DSDT.asl to verify
Device(MCHC) presence after booting to OS.
