Conflict of WiFi/Bluetooth and ADC2

[IoTThinks]

Suggested solution
Need to change GPIO2 and 4 into GPIO32 and 33 in ADC1 to resolve the conflict.
To test GPIO32 and 33 to confirm.

Reference:
The ADC driver API supports ADC1 (8 channels, attached to GPIOs 32 - 39), and ADC2 (10 channels, attached to GPIOs 0, 2, 4, 12 - 15 and 25 - 27). However, the usage of ADC2 has some restrictions for the application:

• ADC2 is used by the Wi-Fi driver. Therefore the application can only use ADC2 when the Wi-Fi driver has not started.

• Some of the ADC2 pins are used as strapping pins (GPIO 0, 2, 15) thus cannot be used freely.
