clk: imx: Rework all imx_clk_hw_composite wrappers
Rather than having multiple different macros for each different type of imx8m_clk_hw_composite, implement them in such a way so we can take advantage the most of the already defined simpler types. Basically, we end up having one low-level __imx8m_clk_hw_composite function, a wrapper to simplify the parents related arguments called _imx8m_clk_hw_composite and then all the types can use those for each specific case.
