Subject: [PATCH 2/3] drm: rcar-du: Add pixel format support

From: Koji Matsuoka <koji.matsuoka.xm@...esas.com>

This patch supports pixel format of RGB332, ARGB4444, XRGB4444,
BGR888, RGB888, BGRA8888, BGRX8888 and YVYU.
VYUY pixel format is not supported by H/W specification.

This patch does not remove existing support for multiplanar YVUY, even
though the hardware does not explicitly provide it, because we support
it through software by swapping the plane buffers.
