include: linux: Add RGB48 formats
Add support for 16-bps (48-bpp) RGB output formats in the uapi headers. These new formats are defined for the RGB and BGR ordering. The corresponding change submitted to the linux-media and DRM mailing lists can be found at: https://lore.kernel.org/linux-media/20240502110503.38412-3-jacopo.mondi@ideasonboard.com/ and https://lore.kernel.org/dri-devel/20240226132544.82817-1-jacopo.mondi@ideasonboard.com/ respectively.
