Warner Losh 888a313927 Remove xscale support.
As discussed in arm@.  This is a scaled back version of the prior
commit because xscale is overlaoded in places to mean armv5 or
similar.  The OLD XSCALE stuff hasn't been useful in a while. The
original committer (cognet@) was the only one that had boards for
it. He's blessed this removal. Newer XSCALE (GUMSTIX) is for hardware
that's quite old. After discussion on arm@, it was clear there was no
support for keeping it.
