drm/amd/display: Fix idle check for shared firmware state
[ Upstream commit 3d066f9547dd58329b526db44f42c487a7974703 ] [WHY] We still had an instance of get_idle_state checking the PMFW scratch register instead of the actual idle allow signal. [HOW] Replace it with the SW state check for whether we had allowed idle through notify_idle.
