[PATCH 015/114] clk: fractional-divider: convert from round_rate() to determine_rate()

[Brian Masney via B4 Relay]

From: Brian Masney <bmasney at redhat.com>

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.
