release and have more of the kernel unlocked we can come back to doing
arcane optimizations to workaround the limitations of the sio hardware.

This is most likely due to the card getting put in the D3 state. This

PCI code. This saves each driver from having to grovel around looking
for the right registers to twiddle.
I should eventually convert the other PCI drivers to do this; for now,
these three are ones which I know need power state handling.

o Add comments in some places to clarify some points.
o Don't typedef sc_p. This isn't usually done in the drivers and may
cause problems in teh future if C goes the C++ route of requiring
one and only one definition for each and every type. Instead use
the current convetion of expanding struct ${1}_softc * inline needed.
o change some comments to be more style(9)-like.
o Define and use DEV2SOFTC to encapsulate storing/getting softc from a
dev_t. This also takes care of the missing cast from the examples.
o Define and use DEVICE2SOFTC, similar to DEV2SOFTC for getting the
softc from a device_t.

We still should have this generate foo_{isa,pci,pccard,cardbus,eisa}.c
and foovar.h from templates of some sort, but I was too lazy to do
that in this commit. I did document it in the comments, however.

The fix works by reverting the ordering of free memory so that the
chances of contig_malloc() succeeding increases.

this gives us several benefits, including:
* easier extensibility- new optional methods can be added to
ac97/mixer/channel classes without having to fixup every driver.
* forward compatibility for drivers, provided no new mandatory methods are
added.
