Subject: [PATCH] drm: vc4: Add 3:3:2 and 4:4:4:4 RGB/RGBX/RGBA formats

The hardware supports the 332 8bpp and 4:4:4:4 16bpp formats,
but the table of supported formats didn't include them.
Add them in.

In theory they are supported for T-format as well as linear,
but without a way to test them just add them as linear for now.
