[PATCH v2 0/4] drm: zynqmp: Make the video plane primary

[Sean Anderson <sean.anderson@linux.dev>]

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.

Changes in v2:
- Allow specifying blend mode default
- Advertise coverage instead of premulti, since that's what the hardware
  supports.
- Set default blend mode to none since that's what the default was
  before this series.
