[RFC PATCH 03/12] clk: sunxi-ng: add CCU driver for V831/V833

V831/V833 are new chips from Allwinner targeting camera market. The
difference between them is similar to V3s/V3, the former one is a
reduced-pin package with co-packaged DDR2 and the latter one is a BGA
package w/o DRAM packaged in.
Add a CCU driver for them. As the user manual didn't have marks for
different chips (V831 and V833 shares the same user manual file), only
implementing a full-functional CCU driver with V833 compatible.

There's a PLL that is called PLL_UNI in the user manual. However a duck
test shows that it is quite similar to PLL_PERI1 on other SoCs: it
functions as parent to some peripherals, occupies the same register
offset with PLL_PERI1 and have the same clock rate configuration with
PLL_PERI1. Here I called it as pll-uni to follow the official document,
but I doubt whether we should call it pll-periph1 to be consistent with
other SoCs.
