Allwinner V3s is a low-end single-core Cortex-A7 SoC, with 64MB
integrated DRAM, and several peripherals.

Changes in v2:
- Used linux-sunxi.org wiki hosted address of V3s datasheet.
Note: the V3s datasheet contains its user manual.

V3s has a similar but cut-down CCU to H3.
Add support for it.

I think I should make a comparsion between V3s and H3 CCU here:
(I won't mention the missing/added clocks here, only list conflicting clocks)
- "bus-ehci0" is at different bit (The bit that is "bus-ehci0" on V3s is
"bus-ehci2" on H3)
- The mux of "ce" is different. (According the view at V3s datasheet by the
author of sun4i-ss, V3s may have sun4i-ss, not sun8i-ce)
- The mux of "de" is different. (V3s do not have "pll-de", but it can mux "de"
to "pll-video")
- Clocks about CSI largely differs. (As V3s is designed as a camera SoC, and
it have an extra "pll-isp")

Allwinner named it datasheet.
For previous SoCs, datasheet will contain info about pins, and user manual
about registers.
But for H3 and V3s, datasheet now contains both pins' info and registers' info.

I remembered some errors' code is directly derived from ccu-sun8i-h3.c,
so I generated a patch file for "clk: sunxi-ng: Add H3 clocks" and run
checkpatch on it:
total: 4 errors, 5 warnings, 1159 lines checked
Should I still get all errors fixed?
