drm/i915: always update ELD connector type after get modes
drm_edid_to_eld() initializes the connector ELD to zero, overwriting the
ELD connector type initialized in intel_audio_codec_enable(). If
userspace does getconnector and thus get_modes after modeset, a
subsequent audio component i915_audio_component_get_eld() call will
receive an ELD without the connector type properly set. It's fine for
HDMI, but screws up audio for DP.
Always set the ELD connector type at intel_connector_update_modes()
based on the connector type. We can drop the connector type update from
intel_audio_codec_enable().
