[PATCH 32/42] drm/amd/display: Update idle optimization handling

[Aurabindo Pillai]

From: Joshua Aberback <joshua.aberback at amd.com>

[How]
 - use dc interface instead of hwss interface in cursor functions, to keep
dc->idle_optimizations_allowed updated
 - add dc interface to check if idle optimizations might apply to a plane
