drm/amd/display: Show link name in PSR status message

[Why]
The PSR message was moved in commit 4321742c394e ("drm/amd/display:
Move PSR support message into amdgpu_dm"). This message however shows
for every single link without showing which link is which.  This can
send a confusing message to the user.

[How]
Add link name into the message.
