clk: core: Force setting the phase delay when no change
This patch reverts commit 023bd7166be0 ("clk: skip unnecessary
set_phase if nothing to do"), fixing two problems:
* in some SoCs, the hardware phase delay depends on the rate ratio of
the clock and its parent. So, changing this ratio may imply to set
new hardware values, even if the logical delay is the same.
* when the delay was the same as previously, an error was returned.
