Yes this is adapted from drivers/clk/sunxi-ng/ccu-sun50i-a64.c, but it is very
different. This is a very stripped down version. I wanted to avoid having to
porting all the clock/gate/div code for sunxi and use as much as possible the
one available in barebox.

Humm...
I could try to get it closer, i would like to not having to copy all the ccu*
drivers, but maybe i could define barebox version of SUNXI_CCU_* macros
