PPC: monitor: add ability to dump SLB entries

Browse Source 
When run with a PPC Book3S (server) CPU Currently 'info tlb' in the
qemu monitor reports "dump_mmu: unimplemented".  However, during
bringup work, it can be quite handy to have the SLB entries, which are
available in the CPUPPCState.  This patch adds an implementation of
info tlb for book3s, which dumps the SLB.
