[PATCH 10/16] drivers/gpio: represent gpio-nomadik as an IRQ controller in DT documentation

[Lee Jones]

Now gpio-nomadik has proper bindings devices initialised by Device Tree
entries are able to use the chained GPIO IRQ lines it provides. This
patch aims to reflect that in the gpio-nmk documentation.
