[PATCH 14/23] powerpc: Provide do_ppc64_personality helper

[Rohan McLure]

Avoid duplication in future patch that will define the ppc64_personality
syscall handler in terms of the SYSCALL_DEFINE and COMPAT_SYSCALL_DEFINE
macros, by extracting the common body of ppc64_personality into a helper
function.
