The old CLK is can't link all hardware clock cell in system that the API of layout such as 'set_parent' can't work as expected. Some hareware clock cell need some flags to prevent some dangerous behaviors, eg: When a clock cell is link to the PMU, the SoC will power-down if the cell is disable. The new CLK can do it, and make the CLK drivers implemented easier from TRM/DataSheet. Signed-off-by: GuEe-GUI <2991707448@qq.com>
