KVM: PPC: booke: Add booke206 TLB trace
The existing kvm_stlb_write/kvm_gtlb_write were a poor match for
the e500/book3e MMU -- mas1 was passed as "tid", mas2 was limited
to "unsigned int" which will be a problem on 64-bit, mas3/7 got
split up rather than treated as a single 64-bit word, etc.

[scottwood@freescale.com: made mas2 64-bit, and added mas8 init]
