Subject: [PATCH 21/27] clk: versaclock3: convert from divider_round_rate()
 to divider_determine_rate()

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()")
