For high-res (8K) or HFR (4K120) displays, using uncompressed pixel
formats like YCbCr444 would exceed the bandwidth of HDMI 2.0, so the
"interesting" modes would be disabled, leaving only low-res or low
framerate modes.
This change lowers the pixel encoding to 4:2:2 or 4:2:0 if the max TMDS

The TI LCDC picks a GPIO line from the device tree to use
for DPMS power on/off. We can switch this to use a GPIO
descriptor pretty easily. Make sure to request the GPIO
"as is" so that the DPMS state that we start (boot) in is
preserved.
