Missing driver for pmc_core on Intel Alder Lake platforms.



[Test Case]

$ ls /sys/bus/platform/drivers/intel_pmc_core

[Where problems could occur]

This adds driver support for a new platform. No regression by the
definition can happen, but it may still suffer from incompleteness of
userspace utility support.

[Other Info]

Alder Lake targets 5.13 kernels, so only Impish & oem-5.13 is proposed.
