drivers/adc: stm32: Update setup_channels() for G4 series

Browse source 
G4 series have specific LL ADC API that discriminate ADC1 and ADC5
channels. Take this into account in adc_stm32_setup_channels().

Additionally, fix this function to use LL defines as argument of macro
__LL_ADC_CHANNEL_TO_DECIMAL_NB, as good practice.
