[ARM] rtc-sa1100: don't assume CLOCK_TICK_RATE to be a constant
As Nicolas and Russell pointed out, CLOCK_TICK_RATE is no more
a constant on PXA when multiple processors and platforms are
selected, change TIMER_FREQ in rtc-sa1100.c into a variable.
Since the code to decide the clock tick rate is re-used from
timer.c, introduce a common get_clock_tick_rate() for this.
