   ## Summary
   
   When an ADC conversion sequence is triggered via the ANIOC_TRIGGER ioctl, 
the priv->current channel counter was not being reset before starting the 
conversion. This meant that if a previous conversion sequence had ended mid-way 
through the channel list (e.g., due to an error or partial read), subsequent 
triggers would resume dispatching au_receive callbacks from the wrong channel 
index, corrupting the channel-to-data mapping reported to the upper half.
   
   This fix resets priv->current to 0 immediately before calling 
adc_startconv() in the ANIOC_TRIGGER handler, ensuring the interrupt handler 
always starts dispatching results from the first channel in the sequence. The 
same fix is applied consistently to both the STM32H5 and STM32H7 ADC drivers, 
which share the same architecture and bug.
