MIPS: Don't overflow cevt-r4k.c calculations at high clock rates.
The 'mult' element of struct clock_event_device must never be wider
than 32-bits. If it were, it would get truncated when used by
clockevent_delta2ns() when this calls do_div().
We can meet this requirement by using clockevent_set_clock() to set
the MULT and SHIFT values.
