Athira Rajeev 83e1ada67a perf powerpc: Add support to expose instruction and data address registers as part of extended regs
This patch enables presenting Sampled Instruction Address Register
(SIAR) and Sampled Data Address Register (SDAR) SPRs as part of extended
registers for the perf tool.

Add these SPR's to sample_reg_mask in the tool side (to use with -I?
option).
