Explicitly use overloaded begin() for I2C master initialization (#2978)

Browse source 
Arduino 2.0.1 and newer support slave and master mode. The two modes
have a begin() method with different signature:

```
// Slave Begin
bool TwoWire::begin(uint8_t addr, int sdaPin, int sclPin, uint32_t frequency)

// Master Begin
bool TwoWire::begin(int sdaPin, int sclPin, uint32_t frequency)
```

Use type casting to make sure that overloaded method for master mode
is used.
