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.
