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_pin_cvt_D0(), since the convertor power state is also fixed here.
- define is_haswell() to replace checking Haswell vendor ID everywhere.
This patch is mostly based on suggestion of David Henningsson.
