feat(boards/3dr/ctrl-n1): configure barometer as DPS368

[TOTON95]

3DR Control-N1 uses the DPS368 barometer variant (not DPS310) on the internal SPI6 bus. Wire the existing dps310 driver's DPS368 mode so the device is probed and registered with the correct device type.

• rc.board_sensors: pass -8 to dps310 start to select the DPS368 variant
• spi.cpp: change the SPI6 baro device type from DRV_BARO_DEVTYPE_DPS310 to DRV_BARO_DEVTYPE_DPS368 so the bus scan matches the driver's request

Verified on hardware: boot log shows dps310 #0 on SPI bus 6, and listener sensor_baro reports device_id: 0x77 = DPS368, bus 6) with valid pressure/temperature readings. Also confirmed the compiled px4_spi_buses table in the built ELF carries devtype_driver = 0x77 rather than the old 0x68 (DPS310).
