Commit d6dbd933 [soc/intel/cannonlake: Use SBI msg to disable HECI1]
switched CNL-based mainboards from using FSP for HECI disablement to SBI
msg, but this causes google/hatch to hang when attempting to unhide p2sb
as part of disabling HECI1 via SBI during SMM, so switch to using
PMC/IPC method. SOC_INTEL_WHISKEYLAKE and SOC_INTEL_COFFEELAKE do not
support PMC disablement method, so they remain using SBI.
Test: build/boot google/hatch, verify HECI1 disabled via console log and
lspci in booted OS.
