ppc: booke206: use MAV=2.0 TSIZE definition, fix 4G pages
This definition is backward compatible with MAV=1.0 as long as the guest does not set reserved bits in MAS1/MAS4. Also, fix the shift in booke206_tlb_to_page_size -- it's the base that should be able to hold a 4G page size, not the shift count.
