V4L/DVB (8689): dpc7146: remove dpc7146 demonstration board driver
Old driver for the dpc7146 demonstration board that is no longer relevant. The last time this was tested on actual hardware was probably around 2002. Since this is a driver for a demonstration board the decision was made (after discussing this with the original author, Michael Hunold) to remove it rather than spending a lot of effort continually updating this driver to stay in sync with the latest internal V4L2 or I2C API.
