[PATCH v5 07/15] clk: at91: sam9x60-pll: use DIV_ROUND_CLOSEST_ULL

[Claudiu Beznea]

Use DIV_ROUND_CLOSEST_ULL() to avoid any inconsistency b/w the rate
computed in sam9x60_frac_pll_recalc_rate() and the one computed in
sam9x60_frac_pll_compute_mul_frac().

Fixes: 43b1bb4a9b3e1 ("clk: at91: clk-sam9x60-pll: re-factor to support plls with multiple outputs")
