It used to be necessary for the phys_addr_t typedef, but now
it doesn't make sense in a few places.

arm/arm64: spinlocks: fix memory barriers
It shouldn't be necessary to use a barrier on the way into
spin_lock. We'll be focused on a single address until we get
it (exclusively) set, and then we'll do a barrier on the way
out. Also, it does make sense to do a barrier on the way in
to spin_unlock, i.e. ensure what we did in the critical section
is ordered wrt to what we do outside it, before we announce that
we're outside.

arm64: implement spinlocks
We put this off, as it wasn't necessary without smp. Now it
is. Only need to do this for arm64, as we've already done it
already for arm.
