V831/V833 are new chips from Allwinner. They're the same die with
different package.

Add a pinctrl driver for them.

The difference between V831/V833 pinctrl is implemented based on the
user manual.

We're not using the wildcard much, and I'd rather be consistent with
the
name / Kconfig option scheme used for the clock driver (and the rest of
the SoCs in a similar situation)

Well, call everything V831, or call everything V833, or call things usable 
on V831 V831 and things only available to V833 V833?
