The IEPCLK_MUX is present on all SoCs whereas the CORECLK_MUX is present only on AM65x SoCs and J721E. Add support for both these CLK muxes. This allows the clock rates and clock parents for these to be controlled through DT leveraging the clk infrastructure for configuring the default parents and rates.
