drm/amd/display: Refactor SubVP cursor limiting logic

Browse source

[WHY]
There are several gaps that can result in SubVP being enabled with
incompatible HW cursor sizes, and unjust restrictions to cursor size due
to wrong predictions on future usage of SubVP.

[HOW]
- remove "prediction" logic in favor of tagging based on previous SubVP
  usage
- block SubVP if current HW cursor settings are incompatible
- provide interface for DM to determine if HW cursor should be disabled
  due to an attempt to enable SubVP
