  The RPM MSG ram includes per-subsystem low-power mode entry/exit/
residence/etc. statistics which are very useful for trying to debug
what I'd call "SoC insomnia", or IOW the plaftorm refusing to drop
the voltage rails to a minimum and gate the non-critical clocks.

This series adds a very short and simple driver to query that data
and expose it through debugfs.

The base used for writing this driver is:
