ALSA: hda-intel - add special 'hwio' model to bypass initialization

Using the 'model=hwio' option, the driver bypasses any codec
initialization and the reset procedure for codecs is also
bypassed. This mode is usefull to enable direct access using
hwdep interface (using hdaverb or hda-analyzer tools) and
retain codec setup from BIOS.

What is the merit over probe_only=1 option...?

I overlooked this possibility. Anyway, skipping the codec reset might help to determine the BIOS settings of codec. I'll update this patch (remove changes in hda_codec.c and use bit 1 in probe_only as skip codec reset).

Thanks, Jaroslav
