clk: zynqmp: pll: Fix zynqmp_clk_divider_determine_rate kerneldoc

After renaming round_rate->determine, kerneldoc does not match anymore,
causing W=1 warnings:

  pll.c:102 function parameter 'req' not described in 'zynqmp_pll_determine_rate'
  pll.c:102 expecting prototype for zynqmp_pll_round_rate(). Prototype was for zynqmp_pll_determine_rate() instead

Fixes: 193650c ("clk: zynqmp: pll: convert from round_rate() to determine_rate()")
