stm32: adc_common_v2: Make EXTSEL and ALIGN definitions per chip

Browse Source 
STM32G4 uses v2 ADC but has EXTSEL and ALIGN fields modified, rather
than making a v3 ADC for these minor changes, the definitions have been
moved to the chip specific headers, so that the common code can work for
G4 onwards.
