pinctrl: single: Use generic parser and #pinctrl-cells for pinctrl-single,pins

commit 4622215fb1dda40bcebab31553765ee9cacb476d upstream.

We can now use generic parser. To support the legacy binding without
missing #pinctrl-cells.

Let's also update the documentation for struct pcs_soc_data while at it
as that seems to be out of date.
