ARM: dts: sun7i: Add basic support for the Cubietruck WiFi module 



The CubieTruck has an AMPAK AP6210 WiFi+Bluetooth module. The WiFi
part is a BCM43362 IC connected to MMC3 in the A20 SoC via SDIO.
The IC also takes a power enable signal via GPIO.

The WiFi module supports out-of-band interrupt signaling via GPIO,
but this is not supported in this patch.
