[Intel-gfx] [PATCH v2 07/17] drm/i915: Use crtc_state->active instead of crtc_state->enable

crtc_state->enable means a crtc is configured, but it may be turned
off for dpms. Until the previous commit crtc_state->active was not
updated on crtc off, but now that we do we should use that for tracking
whether a crtc is scanning out or not.
At this point crtc->active should mirror crtc_state->active,
so some paranoia from the crtc_disable functions can be removed.
Note that intel_set_mode_setup_plls still checks for ->enable,
because all resources that are needed have to be calculated, so
dpms changes will still succeed.
