Input: ads7846 - add support for AD7843 parts
The AD7873 is almost identical to the ADS7846; the only difference is
related to the Power Management bits PD0 and PD1. This results in a
slightly different PENIRQ enable behavior. For the AD7873, VREF should
be turned off during differential measurements.
So, add the AD7873/43 to the list of driver supported devices, and prevent
VREF usage during differential/ratiometric conversion modes.
