drm/radeon/kms: minor fixes for eDP with LCD* device tags (v2)
Some systems have LCD* rather than DFP* device tags in the bios for eDP connectors; notably the new apple iMac. This fixes things up so eDP connectors with either tag will work. v2: fix typo Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
