clk: fixed-factor: Export __clk_hw_register_fixed_factor()

Browse Source 
Make the base registration function for fixed-factor clocks public and
re-implement the various registration functions that are a direct call
to __clk_hw_register_fixed_factor() as macros.

This is similar to how the registration functions of divider, mux and
other clocks are implemented.

Add a new macro clk_hw_register_fixed_factor_pdata() to register
a fixed-factor clock with its parent clock passed as a struct
clk_parent_data.
