The mcp23s08 driver moved to pinctrl recently. It accepts the
bias-pull-up pinctrl property since then. This updates the binding
doc to reflect that.
Thanks to Sebastian Reichel for the working example.

The mcp23s08 driver was moved from gpio to pinctrl. This moves it's
devicetree binding doc as well. So driver and binding doc are in sync
again.
