The usb-clk register is special in that it not only contains clk gate bits,
but also has a few reset bits. This commit adds support for this by allowing
gates type sunxi clks to also register a reset controller.

I know I made you change this, but after having a second look into nr_resets, I
think your original implementation makes more sense. This will break if you use
a mask with holes on it. Sorry :(
No problem, just changed it back :)
