Passes input_id struct to the common probe function for the tsc200x drivers instead of just the bustype. This allows for the use of the product variable to set the input_dev->name variable according to the type of touchscreen used. Note that when we introduced support for TSC2004 we started calling everything TSC200X, so let's keep this quirk.
