Split ADC driver in two halves: ADC(analog ot digital) and TSC(touchscreen). Touchscreen driver is fully functional up to the point of reporting samples. This part will be added once FreeBSD has API for touchscreen. Tested on: Beaglebone Black + 4DCAPE-43T Reviewed by: loos Differential Revision: https://reviews.freebsd.org/D5847
