From: Rafał Miłecki <rafal@xxxxxxxxxx>
Use and extend generic pinctrl binding to include info about pins,
groups & functions.
Northstar platform pins have numbers assigned to them (they are needed
for mux programming) so add a custom "number" property for that.
Extend example to provide a complete binding of a single / random
function.
