[POWERPC] Implement atomic{, 64}_{read, write}() without volatile

Browse source

Instead, use asm() like all other atomic operations already do.

Also use inline functions instead of macros; this actually
improves code generation (some code becomes a little smaller,
probably because of improved alias information -- just a few
hundred bytes total on a default kernel build, nothing shocking).
