sh: clkfwk: modify for_each_frequency end condition 



The end condition of for_each_frequency should care about
both clk_rate_table_round and clk_rate_div_range_round,
and using "correct max size" is a natural idea in later function.
To avoid data over flow, this patch didn't modify
clk_rate_div_range_round side as .max = div_max + 1.
