of/i2c: add dummy inline functions for when CONFIG_OF_I2C(_MODULE) isn't defined

Browse Source 
If CONFIG_OF_I2C and CONFIG_OF_I2C_MODULE are undefined no declaration of
of_find_i2c_device_by_node and of_find_i2c_adapter_by_node will be
available. Add dummy inline functions to avoid compilation breakage.
