clk: zynq: pll: Fix kernel-doc after determine_rate() conversion

Commit 1547747b55d5 ("clk: zynq: pll: convert from round_rate() to
determine_rate()") replaced zynq_pll_round_rate() with
zynq_pll_determine_rate() but left its kernel-doc block behind, so the
block still names the old function and documents the removed @rate and
@prate parameters instead of @req.

Retitle the block and describe @req. The Return: line described a
frequency and referenced the removed @rate; the function returns 0
unconditionally and the rounded rate comes back in @req.

No functional changes.
