msm:disp:dpu1: add support for display for SC7180 target

Add display hw catalog changes for SC7180 target.

Changes in v1:
 - Configure register offsets and capabilities for the
   display hw blocks.

Changes in v2:
 - mdss_irq data type has changed in the dependent
   patch, accommodate the necessary changes.
 - Add co-developed-by tags in the commit msg (Stephen Boyd).

Changes in v3:
 - fix kernel checkpatch errors in v2

Changes in v4:
 - move documentation into seperate patch (Rob Herring).

This patch has dependency on the below series
