[PATCH] drm: xlnx: zynqmp_dp: Support DRM_FORMAT_XRGB8888

[Mike Looijmans]

XRGB8888 is the default mode that Xorg will want to use. Add support
for this to the Zynqmp DisplayPort driver, so that applications can use
32-bit framebuffers. This solves that the X server would fail to start
unless one provided an xorg.conf that sets DefaultDepth to 16.
