New-style I2C drivers require that motherboard-mounted I2C devices are registered with the I2C core, typically at arch_initcall time. This can be done nice and neat by passing the struct i2c_board_info[] through at32_add_device_twi just like we do for the SPI board info. While we've got the hood up, remove a duplicate declaration of at32_add_device_twi() in board.h.
