powerpc/perf: Add support for sampling interrupt register state
The perf infrastructure uses a bit mask to find out valid registers to display. Define a register mask for supported registers defined in uapi/asm/perf_regs.h. The bit positions also correspond to register IDs which is used by perf infrastructure to fetch the register values. CONFIG_HAVE_PERF_REGS enables sampling of the interrupted machine state.
