Currently we disallow the runtime PM of the HD-audio controller if it's bound with HDMI/DP on Nvidia / AMD unless it's for dGPU. This is for keeping the link up to get the proper notification for ELD hotplug. As explained in the commit37a3a98ef6("ALSA: hda - Enable runtime PM only for discrete GPU"), this keep-power-up behavior is rather a stop-gap solution until the ELD notification via audio component. And now we finally got the audio component for these graphics drivers via commitade49db337("ALSA: hda/hdmi - Allow audio component for AMD/ATI and Nvidia HDMI"), so it's time to change. This patch makes HD-audio controller again runtime-suspendable when the device gets bound with audio component in HDMI codec driver. For making it easier to access from the codec driver, move the flag into the common hda_bus object instead of hda_intel flag. Also rename it to keep_power, to indicate the actual meaning.
