drm/display: bridge_connector: move audio_infoframe checks to OP_HDMI

There are DRM_BRIDGE_OP_HDMI_AUDIO bridges (e.g. Lontium LT9611UXC)
which don't implement DRM_BRIDGE_OP_HDMI and don't implement
hdmi_clear_audio_infoframe / hdmi_write_audio_infoframe callbacks.

Move corresponding checks under the DRM_BRIDGE_OP_HDMI condition, making
sure that we require those callbacks only from the bridges which are
actually going to use them.

Fixes: b626b1a ("drm/bridge: refactor HDMI InfoFrame callbacks")
