clk: sprd: composite: Simplify determine_rate implementation

2023-06-14T19:43:26Z

The sprd_div_helper_round_rate() function calls divider_round_rate() which calls divider_round_rate_parent() which calls divider_determine_rate(). This call chain converts back and forth from the rate request structure to make a determine_rate clk_op fit with a round_rate clk_op. Simplify the code here by directly calling divider_determine_rate() instead. This fixes a smatch warning where an unsigned long is compared to less than zero, which is impossible. This makes sprd_div_helper_round_rate() unnecessary as well so simply remove it and fold it into the only caller left.
