  SM6125 is identical to SM6375 except that while downstream also defines
a throttle clock, its presence results in timeouts whereas SM6375
requires it to not observe any timeouts.  This is represented by
reducing the clock array length to 6 so that it cannot be passed.  Note
that any SoC other than SM6375 (currently SC7180 and SM6350) are
unconstrained and could either pass or leave out this "throttle" clock.
