[PATCH 00/11] media: iris: migrate to using global UBWC config

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

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.
