Subject: [PATCH 6/8] clk: imx: Rework all clk_hw_register_divider wrappers

Instead of having multiple inline functions that were calling
clk_hw_register_divider, implement a generic low-level
__imx_clk_hw_divider and implement the rest as macros that
pass on as arguments whatever is needed in each case.
