It is not required yet, but it is always a good idea to move to the new
binding (which will be required somewhen, nevertheless).

I am not sure if I understood what you meant with "updating the board
info". You supply i2c_board_info in your board init code and when the
i2c adapter is initialized, it will call the client drivers
probe-function. Maybe the guide in Documentation/i2c/upgrading-clients
will further help you?
All the best,
Wolfram
