[PATCH 1/2] drm: rcar-du: Add more formats to DRM_MODE_BLEND_PIXEL_NONE support

[Damian Hobson-Garcia]

Add additional pixel formats for which blending is disabling when
DRM_MODE_BLEND_PIXEL_NONE is set.

Refactor the fourcc selection into a separate function to handle the
increased number of formats.
