Add the necessary pinctrl, interrupt property and a suitable sleep config to support Bluetooth wakeup feature.
GPIO mode is configured in sleep state to drive the RTS/RFR line low. If QUP function is selected in sleep state, UART RTS/RFR is pulled high during suspend and BT SoC not able to send wakeup bytes.
