ARM: dts: sun8i: h3: Enable AP6212 WiFi on mmc1 on Nanopi M1 Plus
The WiFi side of the AP6212 WiFi/BT combo module is connected to
mmc1. There are also GPIOs for enable and interrupts.
Enable WiFi on this board by enabling mmc1 and adding the power
sequencing clocks and GPIO, as well as the chip's interrupt line.
