radeon/kms: force rn50 chip to always report connected on analog output
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. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
