[PATCH v4 16/29] drm/msm/adreno: write reserved UBWC-related bits

[Dmitry Baryshkov]

On the latest A8xx Adreno chips several of the bits in the UBWC-related
registers are now hardwired to 1. Currently the driver doesn't write
them because there is no side-effect. In the preparation for the
refactoring in the next patch, write '1' to those bits anyway.
