locking/atomic: microblaze: move to ARCH_ATOMIC

Browse Source 
We'd like all architectures to convert to ARCH_ATOMIC, as once all
architectures are converted it will be possible to make significant
cleanups to the atomics headers, and this will make it much easier to
generically enable atomic functionality (e.g. debug logic in the
instrumented wrappers).

As a step towards that, this patch migrates microblaze to ARCH_ATOMIC,
using the asm-generic implementations.
