Staging/iio/adc/touchscreen/MXS: add interrupt driven touch detection
For battery driven systems it is a very bad idea to collect the touchscreen
data within a kernel busy loop.
This change uses the features of the hardware to delay and accumulate samples in
hardware to avoid a high interrupt and CPU load.
