As there is no way to actually query the hardware for the current clock
rate, now racalc_rate() just returns the last rate that was previously
set. But if the rate was not set yet, we return the bogus rate of 1000Hz.
The branch clocks actually have the same rate as their parent (xo_board),
so just return this rate.
