ADC cannot be used with M5Unified and Arduino3.0.4

```c
#include <M5Unified.h>

void setup() {
  auto cfg = M5.config();
  M5.begin(cfg);
  analogReadResolution(12);
}

void loop() {
  M5.delay(1000);
  M5.Log.println("loop");
}
```

Hang up at analogReadResolution().

```
E (119) ADC: CONFLICT! driver_ng is not allowed to be used with the legacy driver
```

This error occurred.
Therefore, I will use Arduino2.x.
