This reverts commit e996557740. Our HW
guys were able to fix this so it never sees the light of day.

During the ISA 2.06 development the opcode for tlbilx changed and some
early implementations used to old opcode. Add support for a MMU_FTR
fixup to deal with this.

The tlbilx opcode was not matching the Power ISA 2.06 arch spec.
The old opcode was an early suggested opcode that changed during the
2.06 architecture process.

Create a new header that becomes a single location for defining PowerPC
opcodes used by code that is either generationg instructions
at runtime (fixups, debug, etc.), emulating instructions, or just
compiling instructions old assemblers don't know about.
We currently don't handle the floating point emulation or alignment decode
as both are better handled by the specific decode support they already
have.
Added support for the new dcbzl, dcbal, msgsnd, tlbilx, & wait instructions
since older assemblers don't know about them.
