drm/msm/dsi_phy_14nm: convert from divider_round_rate() to divider_determine_rate()

Browse source

[ Upstream commit 1d232f793d ]

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.
