Optimize the pm8916_wdt.c driver a bit by pinging the watchdog using a
write instead of read-modify-write. Also report the reboot reason to
userspace and (temporarily) ping the watchdog from the kernel if it was
already enabled by the bootloader.

  watchdog: pm8916_wdt: Avoid read of write-only PET register
  watchdog: pm8916_wdt: Report reboot reason
