[PATCH v5 4/4] platform/x86/intel/pmc: core: Report duration of time in HW sleep state

[Mario Limonciello]

intel_pmc_core displays a warning when the module parameter
`warn_on_s0ix_failures` is set and a suspend didn't get to a HW sleep
state.

Report this to the standard kernel reporting infrastructure so that
userspace software can query after the suspend cycle is done.
