modem: cellular: configurable initialisation priority

Browse Source 
Make the initialisation priority of cellular modems configurable, and
move it earlier in the sequence by default to provide room for devices
to be initialised later.

The updated default value is set to one earlier than
`GNSS_INIT_PRIORITY`, as LTE modems often embed a GNSS modem, whose
driver may depend on the baseline modem driver (GNSS user pipes, etc).
