[PATCH v3 05/34] clk: at91: update clk_pll_get_best_div_mul to return unsigned long

[Bryan O'Donoghue]

clk_pll_get_best_div_mul() returns a value directly as the return
value to round_rate(). clk_ops->round_rate() has been changed to an
unsigned long so for the sake of completeness and neatness this patch
updates the helper function to return the same data-type.
