clk: composite: add _register_composite_pdata() variants

Browse Source 
Add support for the new way of specifying the clock parents. Add the
two new functions
    clk_hw_register_composite_pdata()
    clk_register_composite_pdata()
to let the driver provide parent_data instead of the parent_names.
