PTC field has 8 bits, PVPE has 4. We plan to use the
"hw/registerfields.h" API with MIPS CPU definitions
(target/mips/cpu.h). Meanwhile we use magic 8 and 4.

We want to move that to mips_cpu_reset() later,
because this is not Malta specific but cpu-specific.
However SMP 'cpus' come from MachineState ("hw/boards.h").
So meanwhile this is early review.
