The GPSDO module is an add-on component about that is about 2cm
square. It mounts in the headers directly behind the GPS antenna port.
If the area is empty, there is no GPSDO. GPS antennae will only have
an effect if the module is populated.

If the GPSDO is not present, but is selected on the osmo-trx command
line anyways, the proper action is to exit gracefully or continue
without using the non-existent GPSDO; error logging should be output
in both cases. Currently, UHD crashes in this event, which is clearly
a bug.
