ALSA: hda-intel - remove model=hwio , use probe_only=3 instead 

The probe_only module parameter skips the codec initialization, too.
Remove the model=hwio code and use second bit in probe_only to
skip the HDA codec reset procedure.

@ -597,6 +597,9 @@ probing, the proc file is available, so you can get the raw codec
information before modified by the driver. Of course, the driver
isn't usable with `probe_only=1`. But you can continue the
configuration via hwdep sysfs file if hda-reconfig option is enabled.
Using `probe_only` mask 2 skips the reset of HDA codecs (use
`probe_only=3` as module option). The hwdep interface can be used
to determine the BIOS codec initialization.
