V4L/DVB (13456): s2250: Change module structure

The s2250-board i2c module was converted to use v4l2-i2c-drv.h in preparation for its subdev conversion. This change prevented the s2250-loader from being initialized within the same module due to the module_init and module_exit function definitions in v4l2-i2c-drv.h. Therefore, s2250-loader is now its own module, and the header for exporting s2250-loader functions is no longer needed. The s2250 i2c module name was "2220-board" in some places, and was changed to "s2250".
