busybox/find-touchscreen.sh: Simplify script and recognize USB devices
Simplify the grep expression, use the more common "grep" command instead of "egrep", avoid forking extra processes, join multiple invokations into a single combined expression. Change the touchscreen regex so that it also recognizes various USB touchscreen controllers and the ad7879 i2c device. Based on code used in OpenPLi and meta-topic.
