Colin Ian King 55570f1a44 gnss: ubx: make struct ubx_gserial_ops static
The structure ubx_gserial_ops is local to the source and does not need
to be in global scope, so make it static.

Cleans up sparse warning:
symbol 'ubx_gserial_ops' was not declared. Should it be static?

Johan Hovold 10f146639f gnss: add receiver type support
Add a "type" device attribute and a "GNSS_TYPE" uevent variable which
can be used to determine the type of a GNSS receiver. The currently
identified types reflect the protocol(s) supported by a receiver:

	"NMEA"	NMEA 0183
	"SiRF"	SiRF Binary
	"UBX"	UBX

Note that both SiRF and UBX type receivers typically support a subset of
NMEA 0183 with vendor extensions (e.g. to allow switching to the vendor
protocol).

Johan Hovold 1ad69f10e3 gnss: add driver for u-blox receivers
Add driver for serial-connected u-blox GNSS receivers.

Note that the driver uses the generic GNSS serial implementation and
therefore essentially only manages power abstracted into three power
states: ACTIVE, STANDBY, and OFF.

For u-blox receivers with a main supply and no enable-gpios, this simply
means that the main supply is disabled in STANDBY and OFF (the optional
backup supply is kept enabled while the driver is bound).

Note that timepulse-support is not yet implemented.
