[PATCH v2 8/8] drm/msm/dpu: add SM8250 to hw catalog

Sat Jul 11 00:47:31 UTC 2020
This brings up basic video mode functionality for SM8250 DPU. Command mode
and dual mixer/intf configurations are not working, future patches will
address this. Scaler functionality and multiple planes is also untested.
