Extend support for the V3U Display Unit. The V3U DU support can be tested on a Falcon-V3U making use of the DSI encoder from Laurent. Patch 1 updates the bindings for the DU to cover the V3U platform. Patch 2 just cleans up in preparation for patch 6, and patch 3 is required for operation on the V3U, however it is functional and should be correct for the D3 and E3 as well, as they also lack external sync. Patch 4 is a further clean up to fix the naming of fields identified as incorrect while developing. Patch 5 splits the RCAR_DU_FEATURE_CRTC_IRQ_CLOCK feature flag into two separate components, allowing the V3U to select RCAR_DU_FEATURE_CRTC_IRQ without RCAR_DU_FEATURE_CRTC_CLOCK. And finally, Patch 6 enables the V3U and connects it to the MIPI DSI encoder. Tests have been run and produce images - but there are artifacts visible and some modes are unavailable, which will need further investigations, but can be done on top of this integration.
