Subject: [RFC v4 4/5] platform/x86/intel/pmc: core: Always capture counters on suspend

Currently counters are only captured during suspend when the
warn_on_s0ix_failures module parameter is set.

In order to relay this counter information to the kernel reporting
infrastructure adjust it so that the counters are always captured.
