kexec/ppc64 Enable early kernel's OPAL calls
When the kernel is built with CONFIG_PPC_EARLY_DEBUG_OPAL set, it is
expecting to get r8 and r9 filled respectively with OPAL base address and
OPAL entry address (arc/power/head_64.S).
On the new powernv platform, having these 2 registers set allows the kernel
to perform OPAL calls before it parse the device tree.
