[RFC v2 2/3] platform/x86/amd: pmc: Report duration of time in deepest hw state

[Mario Limonciello]

amd_pmc displays a warning when a suspend didn't get to the deepest
state and a dynamic debugging message with the duration if it did.

Rather than logging to dynamic debugging the duration spent in the
deepest state, report this to the standard kernel reporting infrastructure
that can be accessed from sysfs.
