iio: stmpe-adc: use of_device_id for OF matching 



The of_device_id was added to allow module autoloading, but it should be
also used to allow driver matching via Devicetree.

This also fixes W=1 warning:
  drivers/iio/adc/stmpe-adc.c:357:34: error: ‘stmpe_adc_ids’ defined but not used [-Werror=unused-const-variable=]
