[PATCH 0/4][SRU][U/OEM-5.13] intel_pmc_core: Add Alderlake support to pmc_core driver

[You-Sheng Yang]

This patchset has a V2[1] that moves all Intel specific drivers into
intel/, therefore pmc_core will be moved into intel/pmc/. That's the
new first patch, and the remaining four are exactly the same except
for the paths. While such rename involves many other intel specific
drivers, I think we can skip such renames in 5.13-{generic,oem}.
