rhel: Provide default powercap and DTPM config settings for Arm

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2126952
Upstream Status: RHEL only
Tested: This is one of a series of patch sets to enable Arm SystemReady IR
 support in the kernel for compliant platforms.  This set cleans up
 powercap and enables DTPM for edge systems to use in thermal and power
 management; this is all in drivers/powercap.  This set has been tested
 via simple boot tests, and of course the CI loop.  This may be difficult
 to test on Arm due to DTPM being a very new feature.  However, this is
 exactly the same powercap framework used by intel_rapl, which should
 continue to function properly regardless.
