[Intel-gfx] [PATCH 10/10] drm/i915: Change .crtc_enable/disable() calling convention

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Just pass the atomic state+crtc to the .crtc_enable()
.crtc_disable(). Life is easier when you don't have to think
whether to pass the old or the new crtc state.
