[dm][clk] fixup the work flow of CLK (#11673)

* [dm][clk] fixup the work flow of CLK

Add RT_CLK_F_SET_RATE_NO_REPARENT so clock providers can preserv
the currently selected parent during rate changes.
Round and re-read the effective clock rate after parent handling,
skip redundant gate toggles and hardware programming when
the target is already active, and fix error handling for parent-clock allocation failures.
