    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.
