Subject[ 032/128] radeon/kms: force rn50 chip to always report connected on analog output
3.2-stable review patch.  If anyone has any objections, please let me know.

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

From: Jerome Glisse <jglisse@redhat.com>

commit 51861d4eebc2ddc25c77084343d060fa79f6e291 upstream.

Those rn50 chip are often connected to console remoting hw and load
detection often fails with those. Just don't try to load detect and
report connect.
