[RFC v2 3/3] platform/x86/intel/pmc: core: Report duration of time in HW sleep state

[Mario Limonciello]

intel_pmc_core displays a warning when a suspend didn't get to a HW
sleep state.

This information is generally useful to userspace as well which may use
it to collect further debugging data. Report this to the standard kernel
reporting infrastructure that can be accessed from sysfs.
