This is my minimalized attempt of setting up pins, groups & functions
bindings.

I've been warned that Linux pinctrl subsystem may require refactoring
before it's ready to handle such bindings properly and that appears to
be correct. I'll need to invest more time into reorganizing Linux
structs. Right now it's not ready for tree-like design and it uses
more-or-less magic numbers to handle pins <-> groups relation.

Meanwhile I'd like to get dt-bindings reviewed & possibly merged. To be
honest - my initial reason for that work was developing U-Boot drivers.

Please kindly review those bindings and optionally treat my WIP work on
Linux implementation as proof of concept.
