Athira Rajeev b4ded42268 powerpc/perf: Fix sampled instruction type for larx/stcx 
Sampled Instruction Event Register (SIER) field [46:48] identifies the
sampled instruction type. ISA v3.1 says value of 0b111 for this field as
reserved, but in POWER10 it denotes LARX/STCX type which will hopefully
be fixed in ISA v3.1 update.

Patch fixes the functions to handle type value 7 for CPU_FTR_ARCH_31.
