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.

---
Resend v2:
- Add collected Acks

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

I can't apply patches 1-2 and 5-6 since they depend on patches 3-4 for
which I'd need an Acked-by: from Lee if I'm to pick them up. Same goes
for patch 7.

By the looks of it there are minor conflicts with the MFD tree, but no
major ones. Perhaps it'd be better for Lee to pick up 3-4 for v4.17-rc1
and ack patch 7, then I can take the rest after v4.17-rc1?

I can pick up 1-2 which are separate from the capture changes and have
no dependencies.
