backport pmc_core

Bug Description

The pmc_core interface /sys/kernel/debug/pmc_core/package_cstate_show indicates which PC state the system enterred. Currently, powertop can't show correct PC state, it only shows PC1 ~ PC3, so we need this interface to check the states.

Backport pmc_core commits from upstream.

Verified on IceLake machines, the interface works.

[Regression Potential]
Low, the pmc_core is not a new driver, the new commits help to expose the values to sysfs interface.
