success with snd_hda and 7.1-STABLE on Mac Pro, default changed.

[George Hartzell]

I upgraded my early-2008 Mac Pro to 7.1-STABLE and Gnome 2.24.3 over
the weekend, it had been tracking -STABLE.

I'd imported the snd_hda driver and had it running with a few tweaks,
which I needed to adjust to get it running under this version of the
driver.

I'm only able to get the rear line-out jack to work, I haven't found
anything combination of ....config values and/or default_unit's that
make the front headphone jack work.

For posterity's sake, here are the details:

  /boot/device.hints (added at the bottom)
  hint.hdac.0.config="gpio0 gpio1"

  /boot/loader.conf
  hw.snd.default_unit=3
