[PATCH v3 2/2] dt-bindings: gpio: Add devicetree binding for IDT 79RC32434 GPIO controller

[Thomas Bogendoerfer]

Add YAML devicetree binding for IDT 79RC32434 GPIO controller

Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>

Changes in v3:
 - renamed to idt,32434-gpio
 - drop ngpio description
 - use gpio0: gpio@50004 in example
