[media] sh_vou: Don't use module names to load I2C modules

With the v4l2_i2c_new_subdev* functions now supporting loading modules
based on modaliases, remove the module names hardcoded in platform data
and pass a NULL module name to those functions.

All corresponding I2C modules have been checked, and all of them include
a module aliases table with names corresponding to what the sh_vou
platform data uses.
