rS298802: Add driver for AM33xx SoC touchscreen

Summary

Add initial support for touchscreen part of ti_adc driver. It does not report actual values to the userland since we do not have API for that but it would be nice to have support ready when API lands in the tree

Test Plan

Enable debug by defining DEBUG_TSC in ti_adc.c
Build kernel and boot on Beaglebone Black with 4dcape-43t
Check if coordiantes are printed when stylus is used on touchscreen

I can't test the touch screen output (no hardware), but changes seem ok.

Thank you Gonzo.

Thanks Luiz,

I was more concerned about affecting current ADC functionality. I tried to make this patch as low-impact as possible. I am going to commit it soon, if you notice any change in ADC behaviour please let me know
