From: Ma Ling <ling.ma@intel.com>

Based on Bspec each encoder has different sharing pipe property,
i.e. Integrated or SDVO TV both will occupy one pipe exlusively,
and sdvo-non-tv and crt are allowed to share one. The patch moves
sharing judgment into differnet output functions, and set right
clone bit.
This will be to vaoid that one pipe is shared by both HDMI.

In this version, set crtc_mask for each output, and update dvo output.
