drm/amd/display: Notify idle link detection through shared state
[Why]
We can hang in IPS2 checking DMCUB_SCRATCH0 for link detection state.
[How]
Replace the HW access with a check on the shared state bit. This will
work the same way as the SCRATCH0 but won't require a wake in the case
where link detection isn't required.
