Subject: [PATCH 0/3] drm: zynqmp: Make the video plane primary

The graphics plane does not support XRGB8888, which is the default mode
X uses for 24-bit color. Because of this, X must be set to use 16-bit
color, which has a measurable performance penalty. Make the video plane
the primary plane as it natively supports XRGB8888. An alternative
approach to add XRGB8888 to the graphics plane is discussed in [1], as
well as in patch 2.
