drm/imx: Add initial support for DCSS on iMX8MQ
This adds initial support for iMX8MQ's Display Controller Subsystem (DCSS).
Some of its capabilities include:
* 4K@60fps;
* HDR10;
* one graphics and 2 video pipelines;
* on-the-fly decompression of compressed video and graphics;
The reference manual can be found here:
https://www.nxp.com/webapp/Download?colCode=IMX8MDQLQRM
The current patch adds only basic functionality: one primary plane for
graphics, linear, tiled and super-tiled buffers support (no graphics
decompression yet), no HDR10 and no video planes.
Video planes support and HDR10 will be added in subsequent patches once
per-plane de-gamma/CSC/gamma support is in.
