Jouni Högander 7caac659a8 drm/i915/psr: Compute PSR entry_setup_frames into intel_crtc_state
PSR entry_setup_frames is currently computed directly into struct
intel_dp:intel_psr:entry_setup_frames. This causes a problem if mode change
gets rejected after PSR compute config: Psr_entry_setup_frames computed for
this rejected state is in intel_dp:intel_psr:entry_setup_frame. Fix this by
computing it into intel_crtc_state and copy the value into
intel_dp:intel_psr:entry_setup_frames on PSR enable.
