evbppc conversion to generic-todr

[Garrett D'Amore <garrett_damore%tadpole.com@localhost>]

I have converted evbppc to generic todr.  For evbppc, this was fairly
straight-forward.  This also removes some now stale files.  Please test,
review and if appropriate commit (or ask me to commit).

I've compile tested all the evbppc kernels, and it looks good so far.

The patch is at ftp://ftp.NetBSD.org/pub/NetBSD/misc/gdamore/evbppc.diff

Thanks!
