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 doesn't work make it depend on CONFIG_PM.

  Reported-by: kernel test robot <lkp@intel.com>
  was also fixed

Also commit header it is "Depend on" not "Select"?
