Andrew Gallatin 7ae6cdbca2 Add support for the DEC_ST6600 family of alphas. This includes the
Compaq XP1000, AlphaServer DS20, AlphaServer DS10, and DP264

This has been tested *only* on XP1000's.  I'll be interested to hear from
owners of other types of DEC_ST6600 alphas.

I'd like to thank Don Rice of Compaq for providing the documentation required
to support this platform on FreeBSD.  I'd also like to thank Doug Rabson for newbus,
and for helping me get a multiple hoses working with newbus.
