[v2,0/9] Add support for RZ/G2UL Display Unit

Message

This patch series aims to add support for RZ/G2UL DU.

The LCD controller is composed of Frame Compression Processor (FCPVD),
Video Signal Processor (VSPD), and Display Unit (DU).

The output of LCDC is connected display parallel interface (DPI) and
supports a maximum resolution of WXGA along with 2 RPFs to support the
blending of two picture layers and raster operations (ROPs)

It is similar to LCDC IP on RZ/G2L SoCs, but does not have DSI interface.

v1->v2:
 * Updated cover letter header "DU IP->Display Unit".
 * Updated commit description related to non ABI breakage for patch#3.
 * Added Ack from Conor for binding patches.
