5.4-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit b46a3d323a5b7942e65025254c13801d0f475f02 ]
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.
