powerpc32: Fix timebase synchronization on 32-bit powermacs
The variable `timebase' used to transfer the current timebase value from one cpu to the other in smp_core99_give/take_timebase was only an unsigned long, i.e. 32 bits on 32-bit machines. It needs to be 64 bits. This makes it a u64, and fixes the issue reported by Kyle Moffett, that the two cpus see wildly different values for the time of day.
