clk: rockchip: drop old_rate calculation on pll rate changes
Previously when everything happened in the set_rate callbacks itself we needed the old_rate value for the possible rate rollback, so that made it easy to also use it in the debug output. Now with the param-handling being done in separate functions, reading and recalculating the current pll rate only to use it in a debug message that won't get displayed in regular cases anyway is quite a waste. Therefore drop that value from the debug output. In the worst case that previous rate will have been displayed on the rate change before. Signed-off-by: Heiko Stuebner <heiko@sntech.de>
