The 'driver' field of the i2c_client struct is redundant and is going to be
removed. The results of the expressions 'client->driver.driver->field' and
'client->dev.driver->field' are identical, so replace all occurrences of the
former with the later. To get direct access to the i2c_driver struct use
'to_i2c_driver(client->dev.driver)'.

This reduces the size of the stack frame when calling request_module().
Performing the sprintf before the call is not needed.

Simplify life for drivers using an encoder-slave, so that they can make
their drm_encoder_helper_funcs const, rather than needing to dynamically
allocate and populate them.

In most use cases the driver will be using the same static config all
the time: interpreting i2c_board_info::platform_data as the default
config we can can save the GPU driver a redundant set_config() call.

Define some helper functions to make easier to detach a KMS encoder
implementation from the drm module of the GPU it's used in. This is
mainly useful for some external I2C encoders known to be present on
cards with GPUs from several different manufacturers.
