[PATCH 3/9] v4l: Add sunxi Video Engine pixel format

[paul.kocialkowski@bootlin.com (Paul Kocialkowski)]

From: Florent Revest <florent.revest@free-electrons.com>

Add support for the allwinner's proprietary pixel format described in
details here: http://linux-sunxi.org/File:Ve_tile_format_v1.pdf

This format is similar to V4L2_PIX_FMT_NV12M but the planes are divided
in tiles of 32x32px.
