[PATCH v2] watchdog: pnx4008: readout watchdog state

[Alexandre Belloni]

Readout the enabled state so it is possible to get the pre-userspace
handler working. Also, avoid disabling the watchdog to ensure it continues
working and triggers if there is an issue later in the boot or if userspace
fails to start.
