Subject[199/200] drm/i915: Dont touch PORT_HOTPLUG_EN in intel_dp_detect()
2.6.34-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Karsten Wiese <fzuuzf@googlemail.com>

commit 6e0032f0ae4440e75256bee11b163552cae21962 upstream.

PORT_HOTPLUG_EN has allready been setup in i915_driver_irq_postinstall(),
when intel_dp_detect() runs.

Delete the DP[BCD]_HOTPLUG_INT_EN defines, they are not referenced anymore.

I found this while searching for a fix for
https://bugzilla.redhat.com/show_bug.cgi?id=528312
