Phase 0: record host bring-up progress on the car unit

Browse Source 
LTE is up over QMI on povo, metered and ranked below Ethernet/WiFi, with
failover tested. CAN interfaces now have stable udev names (can_pcan,
can_onboard) since canN order raced at boot, so references to can1/can0
go. GNSS stays open: gpsd runs but has no fix until an open-sky test,
which is now what blocks the moving map. Kernel-update rebuild steps
are documented for both out-of-tree modules; time sync is pinned to NICT.
