Enablement of LOBF is added in post plane update whenever has_lobf flag is set. As LOBF can be enabled in non-psr case as well so adding in post plane update. There is no change of configuring alpm with psr path. v1: Initial version. v2: Use encoder-mask to find the associated encoder from crtc-state.
