drm/radeon/kms: fix dp_detect handling for DP bridge chips

The HPD pin is not reliable for detecting whether a monitor
is connected or not.  Skip HPD and just use DDC or load
detection.

Fixes phantom VGA connected bugs.

[Michel: fixes phantom VGA bugs on his llano system.]

A PPA of this kernel is available at http://kernel.ubuntu.com/~kernel-ppa/mainline/
It has also been cc'd to the stable kernel tree and should therefore eventually make it's way to oneiric-updates as an SRU.
