Subject: [PATCH 08/10] drm/fourcc: Add definitions for Allwinner vendor and MB32 tiled format

This introduces specific definitions for vendor Allwinner and its
specific MB32 tiled format, an NV12-based format with 32x32 tiles.

This format is the default output format used by the VPU on most
Allwinner platforms.
