drm/msm/sde: add exclusion rect support
Add exclusion rect support for DRM planes. The hardware avoids fetching
data for the excluded region for pipe. This feature is supported from
SDE 4.0 for both linear and UBWC RGB formats. The programming changes
for exclusion rect related to multirect will be done as part of
multirect changes.
