Allwinner SoCs after sun6i-a31 nearly all have a R_CCU in PRCM part.
(V3s and R40 do not have it, as they have even no PRCM)
This patch adds support for the ones on H3/A64.
Some clock/reset values are reserved for easier extending the support to
A31/A23, but for this I think some changes to the PRCM MFD should be made,
see [1] (Although this is only a sketch).
