powerpc: Fix invalid use of register expressions

binutils >= 2.26 now warns about misuse of register expressions in
assembler operands that are actually literals, for example:

  arch/powerpc/kernel/entry_64.S:535: Warning: invalid register expression

In practice these are almost all uses of r0 that should just be a
literal 0.
