ALSA: hda/hdmi: Move runtime PM resume into hdmi_present_sense_via_verbs()
For improving the readability, move the runtime PM handling code from hdmi_present_sense() to hdmi_present_sense_via_verbs(). Now hdmi_present_sense() became symmetric for both audio-component and legacy cases. Just a minor code refactoring.
