staging: mmal_vchiq: Add in the Bayer encoding formats

raspberrypi inclusion
category: feature
bugzilla: 50432

--------------------------------

The list of formats was copied before Bayer support was added.
The ISP supports Bayer and is being supported by the bcm2835_codec
driver, so add in the encodings for them.
