Stephen Boyd 587dd448d9 clk: sprd: composite: Simplify determine_rate implementation
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.
