MMRM clients may set a clock rate which is greater than max supported
rate for the clock. To perform peak power calculations, round the rate
with clk_round_rate() to get the rounded (max supported) value. Use the
client-set value to set the rate to clock driver, which internally
rounds the rate to the supported value also.
