drm/i915: Set crtc/clone mask in different output devices

Browse Source 
Based on Bspec each encoder has different sharing pipe property,
i.e. Integrated or SDVO TV both will occupy one pipe exclusively,
and sdvo-non-tv and crt are allowed to share one. The patch moves
sharing judgment into differnet output functions, and sets the right
clone bit.

This fixes both HDMI outputs choosing the same pipe.
