drivers: adc: stm32: Clear ADRDY before waiting
Clear ADRDY before enabling ADC to ensure the subsequent
wait for ADRDY does not stop prematurely in case ADRDY
was already set.
The "ADC on-off control" sections of the following reference manuals
were consulted. That gives at least one instance per series affected
by this change, even if not every affected MCU is covered.
- RM0438 (STM32L552xx and STM32L562xx)
- RM0351 (STM32L47xxx, STM32L48xxx, STM32L49xxx and STM32L4Axxx)
- RM0434 (STM32WB55xx and STM32WB35xx)
- RM0454 (STM32G0x0)
- RM0440 (STM32G4 Series)
- RM0399 (STM32H745/755 and STM32H747/757)
- RM0433 (STM32H742, STM32H743/753 and STM32H750)
- RM0453 (STM32WL5x)
