hwmon: (twl4030-madc) drop driver

This driver is no longer needed:

 * It has no mainline users
 * It has no DT support and OMAP is DT only
 * iio-hwmon can be used for madc, which also works with DT

If you say yes here you get hwmon support for triton
TWL4030-MADC.
This driver can also be built as a module. If so it will be called
twl4030-madc-hwmon.
