sparc32: refactor smp boot
Introduce a common smp_callin() function to call from trampoline_32.S. Add platform specific functions to handle the platform details. This is in preparation for a patch that will unify the smp boot stuff for all architectures. sparc32 was significantly different to warrant this patch in preparation.
