[PATCH 1/4] clk: clk-gpio: Turn into driver

[Sascha Hauer]

A comment states OF_CLK_DECLARE can't be used for the clk-gpio driver
as it needs to be registered after the GPIO controllers. If that's the
case there is no point in calling of_clk_init() directly from an
initcall. We can better register it as a regular driver which also
makes deep probe work.
