99aa7e2bf7 gpio: remove handling of W_DISABLE pin 
The PinePhone has circuitry that makes this pin active-high, but the
PinePhone Pro doesn't appear to, which means we would need read active
high / active low from the config file. Since the modem works fine
without setting this pin, remove the logic to handle the W_DISBALE pin.

ce0fc25892 at: don't clear the resetting state on sequence end 
If the reset sequence fails, we don't want to transition to the powered
state, instead we should stay in the resetting state so we eventually
timeout and try a gpio reset. If the reset command succeeds the modem
will eventually send RDY and transition the state to STARTED.

Since this might take longer to change the modem state, add 15 seconds
(for a total of 45) to the at reset timeout just in case. It looks like
the modem typically takes about 20 between sending "AT+CFUN=1,1" and
receiving "RDY", so this should be plenty.
