    [MIPS] Fix and cleanup the MIPS part of the (ab)use of CLOCK_TICK_RATE.
    
    This is the clock rate of the i8253 PIT.  A MIPS system may not have
    a PIT by the symbol is used all over the kernel including some APIs.
    So keeping it defined to the number for the PIT is the only sane thing
    for now.
