drm: encoder_slave: use new I2C API
i2c_new_client() is deprecated, use the replacement i2c_new_client_device(). Also, we have a helper to check if a driver is bound. Use it to simplify the code. Note that this changes the errno for a failed device creation from ENOMEM to ENODEV. No callers currently interpret this errno, though, so we use this condensed error check.
