drm/msm/dpu: add support for color processing blocks in dpu driver
This change adds support to configure dspp blocks in
the dpu driver.
Macro description of the changes coming in this patch.
1) Add dspp definitions in the hw catalog.
2) Add capability to reserve dspp blocks in the display data path.
3) Attach the reserved block to the encoder.
