drm/radeon/kms/atom: set sane defaults in atombios_get_encoder_mode()
commit c7a71fc761551dc8be8543f14a90d08cda4e77f9 upstream.
If there was no connector mapped to the encoder, atombios_get_encoder_mode()
returned 0 which is the id for DP. Return something sane instead based on
the encoder id. This avoids hitting the DP paths on non-DP encoders.
