mfd: Don't set mc13783 ADREFMODE for touch conversions

Setting ADREFMODE is utter nonsense, but that's hard to read out of the
spec.  Strange enough it's possible to read x and y values even when
it's set.  When unset you can get values not only for the axes, but also
for contact resistance which allows the touch driver to report pressure
values.
