Subject: [PATCH v2 1/2] clk: introduce (devm_)hw_register_mux_parent_data_table API

Introduce (devm_)hw_register_mux_parent_data_table new API. We have
basic support for clk_register_mux using parent_data but we lack any API
to provide a custom parent_map. Add these 2 new API to correctly handle
these special configuration instead of using the generic
__(devm_)clk_hw_register_mux API.
