libcamera: camera_sensor: Clear camera flips after opening the device
We clear the V4L2_CID_HFLIP and V4L2_CID_VFLIP controls immediately after opening the camera device. This means the camera's Bayer format and mbus codes will be in the sensor's "native" order, and we document this to be the case so that it can be relied upon. Clearing the flips is harmless where sensor flips do not affect the Bayer order. This also fixes a bug in the Raspberry Pi pipeline handler where the native Bayer order was being computed wrongly, but the new behaviour here will be helpful to other pipeline handlers too. A subsequent commit will tidy up the Raspberry Pi pipeline handler in this area as it can now be simplified.
