Adds the GWM brand (Haval H6 2019-26, full ACC/steering support):
- opendbc/car/gwm: brand interface, carstate, carcontroller, gwmcan, values
(adapted to sunnypilot CP_SP API and deprecated field group)
- car.capnp: SafetyModel.gwm @36
- values.py: GWM in the Platform union
- docs_definitions.py: CarHarness.gwm
- safety: gwm.h, SAFETY_GWM 36, registration (behind ALLOW_DEBUG)
- dbc generator for gwm_haval_h6_mk3, torque params for GWM_HAVAL_H6
- car_list.json: Haval H6 now appears in the vehicle selector
- rebuilt panda firmware with the GWM safety mode (DEV-dc833705)
Adds the MG brand (MG 5 EV 2021, dashcam-only) to c3xl-dev's opendbc:
- opendbc/car/mg: brand interface, carstate, carcontroller, mgcan, values
- car.capnp: SafetyModel.mg @35
- values.py: MG in the Platform union
- safety: mg.h, SAFETY_MG 35, registration (behind ALLOW_DEBUG)
- dbc/mg.dbc, torque override for MG_5_EV
- car_list.json: include dashcam-only platforms so MG appears in the
vehicle selector
- rebuilt panda firmware with the MG safety mode (DEV-a53d9321)
FrogPilot handles the GM SystemPowerMode message on both bus 0 and bus 2
(SDGM cars send it on bus 2). C3XL-dev only checked bus 0, so GM cars with
0x1F1 on bus 2 never set ignition_can and the device would not auto power-on.
Mirror FrogPilot: check 0x1F1 on bus 2 as well, keep other exceptions bus-0 only.
