drm/msm/a8xx: Add support for Adreno X2-85 GPU

Adreno X2-85 GPU is found in the next generation of Qualcomm's compute
series chipset called Snapdragon X2 Elite (a.k.a Glymur). It is based
on the new A8x slice architecture and features up to 4 slices. Due to
the wider 12 channel DDR support, there is higher DDR bandwidth available
than previous generation to improve performance.

Add a new entry in the catalog along with the necessary register
configurations to enable support for it.
