drm/amd/display: Add a check for idle power optimization
[why]
Need a helper function to check idle power is allowed
so that dc doesn't access any registers that are power-gated.
[how]
Implement helper function to check idle power optimization.
Enable a hook to check if detection is allowed.
V2:
Add function hooks for set and get idle states.
Check if function hook was properly initialized.
