powerpc/40x: Fix assembler warning about r0
The assembler says:
arch/powerpc/kernel/head_40x.S:623: Warning: invalid register expression
It's objecting to the use of r0 as the RA argument. That's because
when RA = 0 the literal value 0 is used, rather than the content of
r0, making the use of r0 in the source potentially confusing.
Fix it to use a literal 0, the generated code is identical.
