Add the minimal amount of PSR tracking into the crtc state. This allows
precomputing the possibility of using PSR correctly, and it means we can
safely call the psr enable/disable functions for any DP endcoder.
As a nice bonus we get rid of some more crtc->config usage, which we
want to kill off eventually.
