The controller provides a total of 8 analog input
lines, which can be used as:
1. 8 general purpose ADC channels
2. 4 wire TS, with 4 general purpose ADC channels
3. 5 wire TS, with 3 general purpose ADC channels

This patch adds support for TI's ADC driver.
This is a multifunctional device.
Analog input lines are provided on which
voltage measurements can be carried out.
You can have upto 8 input lines.

Add the mfd core driver which supports touchscreen
and ADC.
With this patch we are only adding infrastructure to
support the MFD clients.

Make way for addition of MFD driver.
The existing touchsreen driver is a MFD client.
For better readability we rename the file to
indicate its functionality as only touchscreen.
