target-ppc: Add more stubs for POWER7 PMU registers
In addition to the performance monitor registers found on nearly all
6xx chips, the POWER7 has two additional counters (PMC5 & PMC6) and an
extra control register (MMCRA). This patch adds stub support for them to
qemu - the registers won't do anything, but with this change won't cause
illegal instruction traps accessing them. They're also registered with
their ONE_REG ids, so their value will be kept in sync with KVM where
appropriate.
