[50/54] drm/i915: Use RSEN instead of HTPLG for tfp410 monitor detection.

[Greg KH]

2.6.34-stable review patch.  If anyone has any objections, please let us know.

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

From: Dave Müller <dave.mueller@xxxxxx>

commit f458823b864c6def488f951a79986fa205aba4f1 upstream.

Presence detection of a digital monitor seems not to be reliable using
the HTPLG bit.
