PR28959, obdump doesn't disassemble mftb instruction
Without a -M cpu option given, powerpc objdump defaults currently to
-Mpower10 but -Many is also given. Commit 1ff6a3b8e562 regressed
-Many disassembly of instructions that are encoded differently
depending on cpu, such as mftb which has pre- and post-power4
encodings.
PR 28959
* ppc-dis.c (lookup_powerpc): Revert 2021-05-28 change. Instead
only look at deprecated PPC_OPCODE_RAW bit when -Many.
