Fix decoding of mtacc, dmac, fmac. These files should really get merged

with the ones in BFD and the assembler, but c'est la vie.

+       * am29k-pinsn.c, am29k-opcode.h:  Fix decoding of mtacc, dmac, fmac.
+
        * tm-*.h:  Remove READ_DBX_FORMAT, COFF_FORMAT, and
        READ_MIPS_FORMAT, which have been unused since BFD.  Still
        remaining is COFF_NO_LONG_FILE_NAMES.
