clk: sunxi-ng: add support for the Allwinner H6 CCU
The Allwinner H6 SoC has a CCU which has been largely rearranged. Add support for it in the sunxi-ng CCU framework. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> Acked-by: Maxime Ripard <maxime.ripard@bootlin.com> Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>
