Support 1T segments on ppc

Traditionally, the "segments" used for the two-stage translation used on
powerpc MMUs were 256MB in size.  This was the only option on all hash
page table based 32-bit powerpc cpus, and on the earlier 64-bit hash page
table based cpus.  However, newer 64-bit cpus also permit 1TB segments

This patch adds support for 1TB segment translation to the qemu code.
