clk: qcom: Return highest rate when round_rate() exceeds plan
Some drivers may want to call clk_set_rate() with a very large
number to force the clock to go as fast as it possibly can
without having to know the range between the highest rate and
second highest rate. Add support for this by defaulting to the
highest rate in the frequency table if we can't find a frequency
greater than what is requested.
