drivers: video: formats: include bayer 10/12/14-bits formats

In addition to the 8-bit, introduce all the other bayer formats
described by MIPI-CSI2 specification. The 8-bit bayer formats
description is shortened to just 4 bytes like the other formats,
to help intuition while comparing the different formats.
