arm64: dts: qcom: monaco-arduino-monza: Add Bluetooth UART node

The QCA2066 Bluetooth chip is powered by a board-level 3.3 V supply
provided by the hardware. This change connects the Bluetooth
controller via UART10, and the corresponding GPIO is used to enable
the Bluetooth chip.

basic function test step:
 - bluetoothctl power on/off
 - bluetoothctl scan bredr/le
 - bluetoothctl pair <remote device address>
 - bluetoothctl connect <remote device address>

low-state test and state:
 - rtcwake -d /dev/rtc0 -m no -s 30 && systemctl suspend
