[v1,0/6] clk: sunxi-ng: Allwinner D1 clock support

Message

This series adds support for the D1's CCU and R_CCU.

I attempted to hook up clock parents the "right" way, not using global
names. To accomplish that, I added several new macros. I am open to
comments on this approach. It looks a bit messier, but seems like it
could be less prone to errors.

Applied to sunxi/linux.git (sunxi/clk-for-5.17).

Thanks!
