Since this is handling user provided bpp and depth, we need to sanity check and propagate the EINVAL back rather than assume what the insane client intended and fill the logs with DRM_ERROR. v2: Check both bpp and depth match the builtin pixel format, and introduce a canonical DRM_FORMAT_INVALID to reserve 0 against any future fourcc. v3: Mark up DRM_FORMAT_C8 as being {bpp:8, depth:8}
