[Alexey Brodkin]

This series add support of ARC PGU display controller.
ARC PGU is a quite simple byte streamer that gets data from the framebuffer
and pushes it to hte connected encoder (DP or HDMI).

It was tested on ARC SDP boards (axs101 in particular).

Changes v1 -> v2:
 * Clean-up of DT bindings documentation
 * Added missing "pxlclk" clock in axs10x_mb.dtsi
