[PATCH-next] IIO: ADC: drop unused 'of_id' struct

[Christopher Díaz Riveros]

When CONFIG_STM32_DFSDM_CORE is enabled, stm32-dfsdm-core.o is compiled,
which raises a next warning:

drivers/iio/adc/stm32-dfsdm-core.c: In function ‘stm32_dfsdm_probe’:
drivers/iio/adc/stm32-dfsdm-core.c:245:29: warning: unused variable ‘of_id’ [-Wunused-variable]
  const struct of_device_id *of_id;
                             ^~~~~
