The rzg2l_wdt watchdog driver cannot work w/o CONFIG_PM=y (e.g. the
clocks are enabled though pm_runtime_* specific APIs). To avoid building
a driver that don't work select CONFIG_PM.

depends on PM

The availability of PM is architecture/platform-specific, hence it
must not be selected by individual drivers.

Yes, I did not want to suggest that the driver should _select_ PM.
Sorry that I wasn't more specific.
