Bug detailed description:
---------------------------
DP(Port B) can light up at GRUB step, but black screen after loading I915
driver. With testdisplay -i, it shows DP connected. I have already tried Todd's
hotplug patch, the issue still exsits.

This issue have already tracked at
JIRA(https://jira01.devtools.intel.com/browse/VIZ-3326), now moved to FDO.

The testdisplay -i shows:
