Updated: Linux support for ADS DVD Xpress DX2

In 2007, I had posted a patch for the ADS DVD Xpress DX2 device to work on Linux, but it had been based on an antiquated kernel version, etc.

Since then, someone was nice enough to post an updated version of the driver, but without DVD Xpress DX2 support. I put together a patch which ensures that the drivers now compile and use the new I2C and V4L2 APIs. I can’t guarantee that it works, only that it compiles the driver properly now. Theoretically it should work, but I can’t find my DVD Xpress DX2 to try out the hardware properly.
