clk: nxp: lpc18xx-cgu: convert from round_rate() to determine_rate()

[ Upstream commit b46a3d323a5b7942e65025254c13801d0f475f02 ]

The round_rate() clk ops is deprecated, so migrate this driver from
round_rate() to determine_rate() using the Coccinelle semantic patch
on the cover letter of this series.
