Merge branch 'msm-next-lumag-dpu' into msm-next-lumag

Merge DPU changes, resolving conflicts between branches. Full changelog
will be present in the final merge commit.

DPU:
 - DSPP sub-block flush on sc7280
 - support AR30 in addition to XR30 format
 - Allow using REC_0 and REC_1 to handle wide (4k) RGB planes
