[PATCH v3 7/8] 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.

Signed-off-by: Thierry Reding <treding at nvidia.com>

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