clk: sunxi: Add support for the A100/A133 CCU

The Allwinner A100 SoC has been around for a while, and has now seemingly
been replaced with its close sibling A133.

Add support for the CCU, as far as used by U-Boot proper. Linux has some
basic (clock and pinctrl) support for a while, so we can already use the
existing binding headers.
