archrandom.h includes <asm/machdep.h> to refer ppc_md. This causes
circular header dependency, if generic nodemask.h includes random.h:

Fix it by removing <asm/machdep.h> dependency from archrandom.h
Now as arch_get_random_seed_long() moved to c-file, and not exported,
it's not available for modules. As Michael Ellerman says:
I think we actually don't need it exported to modules, I think it's
a private detail of the RNG <-> architecture interface, not something
that modules should be calling.
