So, in this case, if the id = -1, i2c core will dynamically assign a
bus id to this bus when running, the dynamically assigned bus id is
unknown when writing the code. So, when we use
i2c_register_board_info(int busnum, ...) to register device on
busnum. we don't know which value to be use.

The I2C bus number assigned to the controller should be independant of
the platform device ID used to register the device; a better fix if this
is an issue would be to update the i2c-gpio driver to allow a fixed bus
number to be specified in platform data.

i2c-gpio does support this already.
