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.

[mpe: Mention r0 is almost always the culprit, fold in purgatory change]
