IIO: ADC: stm32-dfsdm: avoid unused-variable warning 



Building with CONFIG_OF disabled produces a compiler warning:

drivers/iio/adc/stm32-dfsdm-core.c: In function 'stm32_dfsdm_probe':
drivers/iio/adc/stm32-dfsdm-core.c:245:22: error: unused variable 'pnode' [-Werror=unused-variable]

This removes the variable and open-codes it in the only place
it gets used to avoid that warning.
