ARM: dts: meson8m2: mxiii-plus: Enable Bluetooth and WiFi support
The MXIII Plus uses an Ampak AP6330 Bluetooth and WiFi combo chip.
Bluetooth is connected to &uart_A and requires toggling GPIOX_20.
WiFi can be routed to either &sdhc or &sdio. Route WiFi to &sdhc
since &sdio is already connected to the SD card. Additionally WiFi
requires toggling GPIOX_11 and GPIOAO_6 as well as enabling the 32kHz
clock signal.
