One way of knowing which hardware we are dealing with is to check the
compatible string. When this must be done at several places, it's best
and certainly more clear to use a helper for that.
Introduce ti_adc_with_touchscreen() to indicate if there is a touchscreen
controller available (meaning it's an am33xx-like ADC). This helper does
not indicate if it is actually used (that is the purpose of the use_tsc
boolean).
Introducing this helper helps making a difference in the code between
what is generic to both types of ADCs and what is specific to the am33xx
hardware before introducing support for the am437x hardware.
