PowerISA v3.1 added three new perfromance
monitoring unit (PMU) speical purpose register (SPR).
They are Monitor Mode Control Register 3 (MMCR3),
Sampled Instruction Event Register 2 (SIER2),
Sampled Instruction Event Register 3 (SIER3).
Patch here adds a new dump function dump_310_sprs
to print these SPR values.
