4465dd0e41 drm/amd/display: Refactor SubVP cursor limiting logic 
[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

7c8fb3b8e9 drm/amd/display: Add hpd_source index check for DCE60/80/100/110/112/120 link encoders 
This patch adds a boundary check for the hpd_source index during the
link encoder creation process for all DCExxx IP's. The check ensures
that the index is within the valid range of the link_enc_hpd_regs array
to prevent out-of-bounds access.
