Enhance the existing pinctrl DT nodes for the Allwinner A64 SoC to
include the new properties the generic, DT-based binding introduced.
This allows any generic driver to support this SoC as well.
The DT nodes stay fully compatible with the old binding, so existing
drivers continue to work without restrictions.
But on top of that new DT users can directly use the information here
and can do without a hardcoded table.
