[ Upstream commit 5406327d43edd9a171bd260f49c752d148727eaf ]

Add Comet Lake to the list of the platforms that intel_pmc_core driver
supports for pmc_core device.

Just like Ice Lake, Comet Lake can also reuse all the Cannon Lake PCH
IPs. No additional effort is needed to enable but to simply reuse them.
