google/link: remove non-existant output port HDMI3
Remove non-existant HDMI3 from output port list in gma-mainboard, since having it there triggers a bug elsewhere in libgfxinit causing the GMBUS controller to end up in a bad state, which results in the touchscreen not working properly under ChromiumOS.
Test: Boot ChromiumOS (r67, r69) on google/link w/libgfxinit, verify touchscreen functional.

Patch Set 1:
I'm not sure where the information came from, but CB:22125 suggests that you can connect HDMI displays to the mini-DP.

Abandoned
looks like this does break pre-OS output via miniDP->HDMI
