target-ppc: Enable frsqrtes on Power7 and Power8
The frsqrtes instruction was introduced prior to ISA 2.06 and is support on both the Power7 and Power8 processors. However, this instruction is handled as illegal in the current QEMU emulation machines. This patch enables the existing implemention of frsqrtes in the P7 and P8 machines.
