drm/amd/display: Multi display cause system lag on mode change
[Why]
DCValidator is created/destroyed repeatedly for cofunctional validation
which causes a lot of memory thrashing, particularly when Driver Verifer
is enabled.
[How]
Implement a basic caching algorithm that will cache DCValidator with a
matching topology. When a match is found, the DCValidator can be
reused. If there is no match, a new one will be created and inserted
into the cache if there is space or an unreference entry can be evicted.
