MIPS: DEC: Do not set up the FPU interrupt if no FPU
Following the arrangement for processors that wire FPU exceptions to the FPE CPU exception handle the case where no FPU is in use -- which for DECstation systems will only ever happen when the "nofpu" kernel option has been used -- do not register the FPU interrupt in such a case either.
