[PATCH v2 6/7] drm/simpledrm: Support the XB24/AB24 format

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

Add XB24 and AB24 to the list of supported formats. The format helpers
support conversion to these formats and they are documented in the
simple-framebuffer device tree bindings.

v2: treat AB24 as XB24 and support both at the same time
