clk: socfpga: agilex5: add clock driver for Agilex5
Add the new Clock manager driver to support new Agilex5 platform. The new
driver got rid of the clk_parent_data structures as there are no 'clock-names'
property in the DT bindings and use parent_names internally. This is based on
the previous feedback from the maintainer.
