calibrated. This fixes the problem where playback and recording do
not run at the correct speed. It probably also eliminates the
need for the hacks/workarounds/sysctl's that were previously
devised to deal with this, but I will leave that for a different
time.

otherwise we might get interrupts and are unable to
handle them properly, which results in a page fault.

sizeof(bus_addr_t) != sizeof(int).

The extra microphone channel capability is part of the "normal" ac97
capabilities and not an extended ac97 capability. Now recording on
codecs without a seperate mic channel works.

(which use the MTX_NETWORK_LOCK macro) and UMA zone locks, a name is used.

returning the format code, which was being interpreted as a failure code.
Fixed. No one seems to have noticed that the maestro driver was broken,
but I'll fix it anyways.

these chips. There is a new hint, hint.pcm.N.hwvol_config, that can be set
to 1 or 0 to select which pins the buttons are connected to. I'm open to
suggestions on where to document this. Also bump the number of playback
channels up to 4.
