powerpc/ppc-opcode: Fix PPC_RAW_TW()
PPC_RAW_TW() is erroneously defined with base code 0x7f000008 instead of 0x7c000008. That's invisible because its only user is PPC_RAW_TRAP() which is 0x7fe00008, but fix it anyway to avoid any risk of future bug. Fixes: d00d762daf12 ("powerpc/ppc-opcode: Define and use PPC_RAW_TRAP() and PPC_RAW_TW()") Reported-by: Naveen N.
