drm/msm: Use the central UBWC config database
As discussed a lot in the past, the UBWC config must be coherent across
a number of IP blocks (currently display and GPU, but it also may/will
concern camera/video as the drivers evolve).
So far, we've been trying to keep the values reasonable in each of the
two drivers separately, but it really make sense to do so centrally,
especially given certain fields (e.g. HBB) may need to be gathered
dynamically.
To reduce room for error, move to fetching the config from a central
source, so that the data programmed into the hardware is consistent
across all multimedia blocks that request it.
