Hi Ben,
You might want to also remove the use of r8 and r9 which are supposed
to contain the OPAL entry and base for debugging purposes. We would also
have to restore them before booting the kernel.
I'd prefer that to be a separate change, if that's okay - it'd require
us to change the kentry

We use r6 and r7 for epapr boot, but the current pre-C init will clobber
both of these.
This change does a simple replacement, of r6 - r12 and r7 - r13, so
that we hit platform init with these registers intact.
