drm/amd/display: enable idle optimizations for linux (MALL stutter)
[Why]
We can only use this feature when the display is idle. When active vblank
irq count is 0 we know all the displays are idle.
[How]
-Add a active vblank irq counter
-Update the counter when we enable/disable vblank irq
-if vblank irq count is 0 we can consider mall stutter
