ARM: dts: stm32: Update to generic ADC channel binding on DHSOM systems

Browse source 
[ Upstream commit 9bcfc3cdc903485a52c6f471f4ae96a41fa51803 ]

The generic ADC channel binding is recommended over legacy one, update the
DT to the modern binding. No functional change. For further details, see
commit which adds the generic binding to STM32 ADC binding document:
'664b9879f5 ("dt-bindings: iio: stm32-adc: add generic channel binding")'
