This series fixes a race condition observed when using several ADCs with DMA
and irq.
There's a precusor patch to the fix. It keeps registers definitions as a whole
block, to ease readability and allow simple (readl) access path to EOC bits in
stm32-adc-core driver.

---
Changes in v2:
- Add a precursor patch to follow Jonathan's comment on readability
