drivers: gnss: nmea_generic: implement basic power management

Browse source 
As of now only the resume action is supported, and doesn't perform
any power action on the GNSS modem.
It allows to initialize the GNSS driver later than it would otherwise
be.

Also, the driver now runs a modem-specific chat script on resumption.

General Purpose I/O (GPIO)
==========================
GNSS
====
* Basic power management support has been added to the ``gnss-nmea-generic`` driver.
If ``CONFIG_PM_DEVICE=y`` the driver is now initialized in suspended mode and the
application needs to call :c:func:`pm_device_action_run` with :c:macro:`PM_DEVICE_ACTION_RESUME`
to start up the driver.
