drm/i915/chv: Configure crtc_mask correctly for CHV
On CHV pipe C can driver only port D, and pipes A and B can drivbe only ports B and C. Configure the crtc_mask appropriately to reflect that. v2: Moar braces (Jani) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Antti Koskipää <antti.koskipaa@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
