Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Cleanups for sys/mips/rmi/bus_space_rmi.c
- remove pci related code from bus_space_rmi.c, we will have another
file for PCI bus space functions which will do byte-swapping.
- remove local SWAP implementation
- added TODO stub for unimplemented functions

Attempt to cope with the dev/rmi -> mips/rmi/dev move.

Merge from projects/mips to head by hand:

Copy over the support files (except sys/conf and sys/mips/conf) for
RMI XLR processor support. This port has been contributed by RMI and
brought up to date by Randal Stewart (rrs@). This port is a work in
progress, and there might still be significant changes. The port
makes it to multi-user, but is still early beta.

Ok With this commit we actually get through
the mi_startup (or to the last of it).. and
hit a panic after :

uart0: <16550 or compatible> on iodi0
Trap cause = 2 (TLB miss....)

I did have to take the pci bus OUT of the
build to get this far, hit a cache error with
the PCI code in. Interesting thing is the machine
reboots too ;-)

white space changes

ok we now get so that the uart init's and we can print. We
cannot set baud rate as they did in 6.4, this hoses things and
we loose our 38400 default term.

We now lock somewhere in tcinit.
