drm/i915/dp: Use crtc_state->enhanced_framing properly on ivb/hsw CPU eDP

Browse Source 
Looks like I missed the drm_dp_enhanced_frame_cap() in the ivb/hsw CPU
eDP code when I introduced crtc_state->enhanced_framing. Fix it up so
that the state we program to the hardware is guaranteed to match what
we computed earlier.
