I²C Configured in Fast Mode by Default

[rei-vilo]

I²C is configured in fast mode 400 kHz by default.

Line 123 in 0faf18b

params.bitRate = I2C_400kHz;

Provide standard mode 100 kHz for compatibility and fast mode plus 1 MHz as well.

This requires us to sync with the Arduino Wire API which introduced a setClock() function to set the clock to a value other than the standard 100kHz. When this is implemented, we can default the clock to 100kHz allowing faster clocks through the setClock() API.
