drm/msm/mdp5: subclass msm_mdss for mdp5
SoCs having mdp5 or dpu have identical tree like
device hierarchy where MDSS top level wrapper manages
common power resources for all child devices.
Subclass msm_mdss so that msm_mdss includes common defines
and mdp5/dpu mdss derivations to include any extensions.
Add mdss helper interface (msm_mdss_funcs) to msm_mdss
base for mdp5/dpu mdss specific implementation calls.
This change subclasses msm_mdss for mdp5, dpu specific
changes will be done separately.
Changes in v3:
- Added Archit's R-b
