target/mips: Remove XBurst Media eXtension Unit dead code
All these unimplemented MXU opcodes end up calling
gen_reserved_instruction() which is the default switch
case in decode_opc_mxu().
The translate.c file is already big enough and hard to maintain,
remove 1300 lines of unnecessary code and /* TODO */ comments.
