FreeBSD/alpha. The most significant item is to change the command

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.
a BSD4.4Lite1 feature, not a FreeBSD feature. <sys/ioctl.h> is a
compatibility misfeature.
Moved NPCI ifdef. This file didn't compile if NPCI <= 0. It shouldn't

of drivers without buses by generating null objects, and many drivers
do it.
Removed unused includes.
