Add nop variants of i2c_find_device_by_fwnode(),
i2c_find_adapter_by_fwnode() and i2c_get_adapter_by_fwnode() for use
without CONFIG_I2C.

Hi Wolfram, others,
This is to support COMPILE_TEST (drivers/media/pci/intel/ipu-bridge.c for
instance). Alternatively we'd need #ifdefs. Similar OF functions have
dummies, too.
We currently get:
ERROR: modpost: "i2c_acpi_new_device_by_fwnode" [drivers/media/pci/intel/ipu-bridge.ko] undefined!
ERROR: modpost: "i2c_find_device_by_fwnode" [drivers/media/pci/intel/ipu-bridge.ko] undefined!
