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()")
