platform/x86/intel/pmc: Show live substate requirements

Browse source

While debugging runtime s0ix, we do need to check which required IPs
are not power gated. This patch adds code to show live substate status
vs requirements in sys/kernel/debug/pmc_core/substate_requirements to
help runtime s0ix debug.
