pieeprom-2025-10-08: 2711: Fix accidental set of PM_RSTS bit 5 when stopping watchdog (latest)

Browse Source 
* Fix accidental set of PM_RSTS bit 5 when stopping watchdog
  Fix an issue in the watchdog code where the raw PM_RSTS value
  was used as partition number. If HADWRF (bit 5) was set (on reboot)
  this could cause bit 10 to be set. If an OS didn't clear the partition
  flags on reboot then this could end up being treated as request to
  boot from partition 32.
