[PATCH 04/05][RFC] clk: fixed-factor: Pass struct clk_init_data

[Magnus Damm <magnus.damm@gmail.com>]

From: Magnus Damm <damm+renesas@opensource.se>

Break out a function named clk_register_fixed_factor_init()
that takes a struct clk_init_data pointer that may or may not
contain a populated parent array.

Useful for SoC-specific clock drivers that want to pass an
populated parent array during clock registration.
