Change in osmo-e1d[master]: e1d: stat_items for the GPS-DO related bits

laforge has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-e1d/+/27830 ) Change subject: e1d: stat_items for the GPS-DO related bits ...................................................................... e1d: stat_items for the GPS-DO related bits It is interesting from a monitoring point of view to be able to correlate the GPSDO state with other performance counters we export. While each GPS-DO only exists once per icE1usb, we still export the state per line, to make it easy for external monitoring to have one set of counters per line.
