clk: meson: introduce meson-clkc-utils

Browse source 
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.
