cpu: Move cpu_index field to CPUState

Browse source 
Note that target-alpha accesses this field from TCG, now using a
negative offset. Therefore the field is placed last in CPUState.

Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change.

Move common parts of mips cpu_state_reset() to mips_cpu_reset().

Acked-by: Richard Henderson <rth@twiddle.net> (for alpha)
[AF: Rebased onto ppc CPU subclasses and openpic changes]
