ALSA: via82xx: add option to disable 500ms delay in snd_via82xx_codec_wait
There's a large 500ms delay in snd_via82xx_codec_wait() that, at least
on my hardware, appears to be unnecessary. The rest of the init of
the card works without logging any warnings or errors and both audio
and mixer settings work.
This adds an "nodelay" parameter to disable this (undocumented in the
code) large delay improving bootup time by 489-500ms.
