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),

Patch here adds a new dump function dump_310_sprs
to print these SPR values.

Why not all on one line like many of the others?
Sure, will change this to one line
