Let's introduce a new module called meson-clkc-utils that will contain shared utility functions for all Amlogic clock controller drivers. The first utility function is a replacement of of_clk_hw_onecell_get in order to get rid of the NR_CLKS define in all Amlogic clock drivers. The goal is to move all duplicate probe and init code in this module.
