Subject: platform/x86: intel_pmc_core: Add Intel Elkhart Lake support
Git-commit: 554f269f0f384d34f7e8052242df3b97be325924
Patch-mainline: 5.6-rc1
References: jsc#SLE-12700
Add Intel Elkhart Lake to the list of the platforms that driver supports
for the PMC device.
Just like Ice Lake and Tiger Lake, Elkhart Lake can also reuse all the
Cannon Lake PCH IPs. Also, it uses the same PCH IPs of Tiger Lake, no
additional effort is needed to enable but to simply reuse them.
