ALSA: hda - unmute pin amplifier in infoframe setup for Haswell
When Gfx driver reconnects a port and transcoder, the pin amplifier will
be muted. To enable sound, the pin amp need to be unmuted.
This patch
- moves pin amp unmuting from stream preparing to hdmi_setup_audio_infoframe().
So if port:transcoder reconnection happens during stream playback, the ELDV
unsol event can stil trigger pin's amp unmuting when re-setting up audio
info frame.
- remove reading pin amp status before unmuting for speed-up, since pin amp
should always be unmuted.
- rename haswell_verify_pin_D0() to haswell_verify_D0(), since the convertor
power state is also fixed here.
This patch is mostly based on suggestion of David Henningsson.
