ppc/spapr: Move GPRs setup to one place
At the moment "pseries" starts in SLOF which only expects the FDT blob pointer in r3. As we are going to introduce a OpenFirmware support in QEMU, we will be booting OF clients directly and these expect a stack pointer in r1, Linux looks at r3/r4 for the initramdisk location (although vmlinux can find this from the device tree but zImage from distro kernels cannot). This extends spapr_cpu_set_entry_state() to take more registers. This should cause no behavioral change.
