dt-bindings: PCI: toshiba,tc9563: Document embedded GPIO controller
The TC9563 PCIe switch embeds a GPIO controller providing 37 GPIO lines,
accessed through the switch's I2C interface.
The controller is integrated in the switch rather than being a separate
device, so expose it by adding the gpio-controller and #gpio-cells
properties to the switch node itself, and extend the example to show the
downstream ports' reset-gpios being driven from those lines.
