drm/i915: push DDI CRT underrun reporting on disable to encoder
CRT being the only PCH encoder, we can simplify the crtc disable by pushing the PCH encoder specific parts to CRT encoder. v2: add hsw_disable_crt (Daniel), rebase Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1ecbbb946f7b3782ee3d97f0ec2fe4758c349311.1507200657.git.jani.nikula@intel.com
