This provides a free software alternative to raspberrypi-power.c's
firmware calls to manage power domains. It also exposes a reset line,
where previously the vc4 driver had to try to force power off the
domain in order to trigger a reset.

The PM block that the wdt driver was binding to actually has multiple
features we want to expose (power domains, reset, watchdog). Move the
DT attachment to a MFD driver and make WDT probe against MFD.
