The .set_rate() callback for the SD clocks is always called with a valid
clock rate, returned by .round_rate(). Hence there is no need to
iterate through the divider table twice: once to repeat the work done by
.round_rate(), and a second time to find the corresponding divider
entry.
Just iterate once, looking for the divider that matches the passed clock
rate.
