Description

Hi

This is replacing #9560, not only for STM32L0 but for all STM32 families.
Internal channels use is enabling ADC "internal path" which needs to be disabled after measurement.

@RobVlaar please have a look on this new correction

@LMESTM please take it into account for #9814

@jeromecoutant - I think #9814 is not far from being merged, I'd prefer this PR to be updated once STM32WB is merged.

@cmonr @jeromecoutant Actually #9814 is being blocked.
Please proceed with the review / merge of this PR and I will apply the same in #9814 or after it ...
