Adding the following formats
- DRM_FORMAT_RX106
- DRM_FORMAT_GXRX106106
- DRM_FORMAT_RX124
- DRM_FORMAT_GXRX124124
- DRM_FORMAT_AXBXGXRX124124124124
- DRM_FORMAT_RX142
- DRM_FORMAT_GXRX142142
- DRM_FORMAT_AXBXGXRX142142142142
They are useful for communicating Bayer data between ISPs and GPU by emulating
GL_R16UI and GL_RG16UI formats
