Subject: [PATCH v5 6/7] i2c: core: Deprecate of_node in struct i2c_board_info

Two members of the same or quite similar semantics is quite confusing
to begin with. Moreover, fwnode covers all possible firmware descriptions
that Linux kernel supports. Deprecate of_node in struct i2c_board_info,
so users will be warned and in the future there is a plan to convert
the users and remove it completely.
