platform/x86/amd: pmc: Report duration of time in hw sleep state 



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 so that userspace software can query after the
suspend cycle is done.
