Subject: [PATCH V7 03/18] tools/perf: Update TYPE_STATE_MAX_REGS to include max of regs in powerpc

TYPE_STATE_MAX_REGS is arch-dependent. Currently this is defined
to be 16. While checking if reg is valid using has_reg_type,
max value is checked using TYPE_STATE_MAX_REGS value. Define
this conditionally for powerpc.
