ALSA: hda - Delay HDMI presence reports while waiting for ELD information

There is a small gap between the jack detection unsolicited event and
the time the ELD is updated.  When user-space queries the HDMI ELD
immediately after receiving the notification, it might fail because of
this gap.

For avoiding such a problem, this patch tries to delay the HDMI jack
detect notification until ELD information is fully updated.  The
workaround is imperfect, but good enough as a starting point.

ALSA: compress: fix drain calls blocking other compress functions (v6)

The drain and drain_notify callback were blocked by low level driver
until the draining was complete. Due to this being invoked with big
fat mutex held, others ops like reading timestamp, calling pause, drop

So to fix this we add a new snd_compr_drain_notify() API. This would
be required to be invoked by low level driver when drain or partial
drain has been completed by the DSP. Thus we make the drain and

that other ops can go ahead.

For Valleyview display codec, if an unused pin chooses an assgined converter
selected by a used pin, playback on the unused pin can also give sound to the
output device of the used pin. It's because data flows from the same convertor
