AP_GPS: DroneCAN GPS_AUTOCONFIG does not revert from moving baseline to standard

[yuri-rage]

Bug report

Issue details
When using AP_Periph GPS modules (Here3+) with GPS_AUTOCONFIG=2, GPS_TYPE=22, and GPS_TYPE2=23, ArduPilot will correctly set the periph node GPS types to 17 and 18.

However, if the user subsequently reverts to GPS_TYPE=9, ArduPilot will fail to detect the periph GPS until it is manually set back to GPS_TYPE=1 within the CAN parameter list.

Same problem and same solution with Plane V4.3.7

Further discussion seems to indicate that Here model DroneCAN modules do not function properly at all in moving baseline configurations.

Seems I had a bit of a misconception regarding the available feature set on the Here3+. They are not compatible with a moving baseline config, which probably explains some of this.

However, HerePro modules may be similarly afflicted - request this issue be kept open until it can be confirmed that HerePro modules function properly with a moving baseline configuration. At present, it seems they do not.

@yuri-rage I am looking into the issue, you are right trying to set Here3+ as moving baseline will cause issues, most likely they will fail to configure at all. As far as HerePro is concerned, I am looking into the issue.
