Add AST2700 clock controller driver and also use axiliary
device framework register the reset controller driver.
Due to clock and reset using the same register region.

It would be easier to read if these things were tabbed out a little.

Isn't this the default divider setting for struct clk_divider?

This has no parent? Why is parent_names set to an empty array?

What if it is 0? Were we supposed to return an error? Why isn't HPLL a
different type of PLL so that this function can be broken up into two
PLL registration functions?

Just
	clk_data = device_get_match_data(dev);

What is being populated? Isn't there always clk_data?
