watchdog: bcm2835_wdt: consider system-power-controller property
Until now all Raspberry Pi boards used the power off function of the SoC. But the Raspberry Pi 400 uses gpio-poweroff for the whole board which possibly cannot register the poweroff handler because the it's already registered by this watchdog driver. So consider the system-power-controller property for registering, which is already defined in soc/bcm/brcm,bcm2835-pm.txt . Signed-off-by:Stefan Wahren <stefan.wahren@i2se.com> Reviewed-by:
