disp: msm: sde: update HFC layer checks

Update HFC layer checks to handle partial update. Layer checks
should compare against ROI when partial update is enabled.
Layer checks should compare against full panel height when
destination scaler is enabled. Destination scaler and PU
concurrency is not supported.
