[PATCH 6.19 551/781] clk: versaclock3: convert from divider_round_rate() to divider_determine_rate()

From: Brian Masney <bmasney@redhat.com>

[ Upstream commit 56c1cfb488cc17944c200edad96191a70a3783ba ]

The divider_round_rate() function is now deprecated, so let's migrate
to divider_determine_rate() instead so that this deprecated API can be
removed.

Note that when the main function itself was migrated to use
determine_rate, this was mistakenly converted to:

req->rate = divider_round_rate(...)

This is invalid in the case when an error occurs since it can set the
rate to a negative value.

Fixes: 9e3372b2ebac ("clk: versaclock3: convert from round_rate() to determine_rate()")
