Emmanuel Vadot f5d1d20574 Add clkng driver for Allwinner SoC
Since Linux 4.9-4.10 DTS doesn't have clocks under /clocks but only a ccu node.
Currently only H3 is supported with almost the same state as HEAD.
(video pll aren't supported for now but we don't support video).
This driver and clocks will also be used for other SoC (A64, A31, H5, H2 etc ...)
