[PATCH v3 2/2] ARM: sun8i: h2+: specify wifi interrupts for Orange Pi Zero

From: Sergey Matyukevich <geomatsi at gmail.com>

The Orange Pi Zero board has Allwinner XR819 SDIO wifi chip. The board
dts file provides a node enabling mmc1 controller, and a out-of-band
interrupt line of the chip is also connected, although the chip also
supports in-band interrupt.

The current out-of-tree driver is hardcoded to use out-of-band interrupt
as default, and it needs to be modified to use the in-band interrupt.

This commit adds the out-of-band interrupt line into the device tree.
