This series adds support for capture to stm32-pwm driver.
Capture is based on DMAs.
- First two patches are precursor patches
- Subsequent two patches add support for requesting DMAs to MFD core
- Next three patches add support for capture to stm32-pwm driver
- This has been tested on stm32429i-eval board.

---
Changes in v2:
- Abstract DMA handling from child driver: move it to MFD core
- Rework pwm capture routines to adopt this change
- Comment on optional dma support, beautify DMAs probe
