arm64: dts: meson-gxbb: nanopi-k2: Enable Bluetooth

From: Chen-Yu Tsai <[email protected]>

The NanoPi K2 has a AP6212 WiFi+BT combo module. The WiFi portion is already enabled. The BT part is connected via UART and I2S.

Enable the UART and add a device node describing the Bluetooth portion of the module.

Changes since v2:
- dropped alias for uart_A
- added Martin's reviewed-by

Changes since v1:
- added uart-has-rtscts property
- added alias for uart_A
