hppa: __cpu_simple_lock membar audit.

__cpu_simple_lock(9): Omit needless barriers in init.

It is, and always has been, the caller's responsibility to ensure the
lock is initialized before it can be used -- otherwise the memory
could hold garbage; it is nonsensical to even attempt locking
operations on it before initialization.

So there's no need to issue explicit barriers here.  The barrier
seems to have been introduced in sys/arch/alpha/alpha/lock_machdep.c
rev. 1.1 (since moved to inline asm in alpha/include/lock.h) and then
copied & pasted into several other architectures.

Don't use structure copy in __cpu_simple_lock_init. Set the array elements
to __SIMPLELOCK_RAW_UNLOCKED instead.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
