[PATCH 6.19 552/781] clk: x86: cgu: convert from divider_round_rate() to divider_determine_rate()

From: Brian Masney <bmasney@redhat.com>

[ Upstream commit bb1b0e63dbbd7150324cb4d6aef7854dbe26a617 ]

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: f7a6bed91a19 ("clk: x86: cgu: convert from round_rate() to determine_rate()")
