re: kern/44060 (iwn wireless works for awhile, then fails)

FWIW, i ported -current driver back to netbsd-5.  i haven't tried
to boot the kernel but it does build.

        http://www.netbsd.org/~mrg/if_iwn-5.diff

i'll see about setting up a netbsd 5 install on my laptop with iwn
to see if to works, but if someone else can test that would be
even better...

the change isn't small, but it is almost a direct copy of the driver
from -current.  the only changes i had to make after copying were:

        - pmf resume API change

        - bpf_attach2 -> bpfattach2

        - also copy new pcidevs parts

        - also copy new pcireg.h PCIE parts
