[PATCH v2 resend 1/3] ASoC: hdac_hdmi: report codec link up/down status to bus

[Kai Vehmanen <kai.vehmanen@linux.intel.com>]

Report codec power status to the HDA codec bus from runtime pm
suspend and resume callbacks. This is required to implement
runtime idle logic that relies on 'codec_powered' field of hdac_bus
to be maintained for all codecs.
