UPSTREAM: i2c: of: Populate fwnode in of_i2c_get_board_info()

Browse Source 
This allows the of_devlink feature to work across i2c devices too. This
avoid unnecessary probe deferrals of i2c devices, defers consumers of
i2c devices till the i2c devices probe, and allows i2c drivers to
implement sync_state() callbacks.
