ARM: dts: sun6i: hummingbird: Enable the onboard WiFi module

Browse Source 
The Hummingbird A31 has an AMPAK AP6210 WiFi+Bluetooth module. The
WiFi part is a BCM43362 IC connected to MMC1 in the A31 SoC via SDIO.
The IC also takes a power enable signal via GPIO. This is supported
with the new power sequencing bindings.

The WiFi module supports out-of-band interrupt signaling via GPIO,
but this is not enabled yet.
