I2C Driver
----------
For registering the `/dev/i2c-0` device, a wrapper function is provided,
``bbb_register_i2c_0()`` similarly ``bbb_register_i2c_1()`` and
``bbb_register_i2c_2()`` are respectively used to register `i2c-1` and `i2c-2`.
The Beagle has the `i2c-0` device registered at initialization. For registering
`i2c-1` and `i2c-2` ``bbb_register_i2c_1()`` and
``bbb_register_i2c_2()`` wrapper functions are respectively used.
For registering an I2C device with a custom path (say `/dev/i2c-3`) the
function ``am335x_i2c_bus_register()`` has to be used.
