[POWERPC] Reworking machine check handling and Fix 440/440A
This adds a cputable function pointer for the CPU-side machine check handling. The semantic is still the same as the old one, the one in ppc_md. overrides the one in cputable, though ultimately we'll want to change that so the CPU gets first. This removes CONFIG_440A which was a problem for multiplatform kernels and instead fixes up the IVOR at runtime from a setup_cpu function. The "A" version of the machine check also tweaks the regs->trap value to differenciate the 2 versions at the C level.
