This patch adds device tree support for the netxbig LEDs. This also introduces a additionnal DT binding for the GPIO extension bus (netxbig-gpio-ext) used to configure the LEDs. Since this bus could also be used to control other devices, then it seems more suitable to have it in a separate DT binding.
