Having UBWC configuration in the driver is error prone. For example, the driver specifies fixed values for HBB, while the actual value might depend on the DDR type. Stop defining UBWC data in the iris driver and use the global UBWC configuration registry.
Merge strategy: either merge SoC bits directly through the media tree (with Bjorn's ack) or merge to the media tree through the immutable tag. The drm patches will follow depending on the way the SoC patches are merged. Note: the patches are compile-tested only because of the lack of the Gen2 hardware at hand.
