Log Message:
Changes to sys/arch/mips from ARC port, from Noriyuki Soda 
<soda%sra.co.jp@localhost>.
Adds (most) support for ARC platform to port-independent mips code.

Some changes (e.g., clean up of overlapping CPU/FPU ids) inspired by
comparison to the OpenBSD 2.1 codebase of Soda's ARC port.

Open issues:
* Still no support for r4600 or mipsIV CPUs with two-way L1 cache.
Code derived from Per Fogelstrom's OpenBSD source  doesn't work
on mips3 pmaxes with L2 cache.

* Still some port-specific  #ifdefs, for interrupt enable and
pmax L2 cache-size.  Needs more thought, but overlaps with
work-in-progress by Tohru and Tsubai on spl()s and related stuff.
