drm/amd/display: Return invalid state if GPINT times out
[Why]
GPINT timeout is causing PSR_STATE_0 to be returned when it shouldn't.
We must guarantee that PSR is fully disabled before doing hw programming
on driver-side.
[How]
Return invalid state if GPINT command times out. Let existing retry
logic send the GPINT until successful.
