- Add missing pinctrl description. Support is made optional as dfsdm
  may use internal sources (e.g. via registers)
- Fix typo in IIO STM32 DFSDM filter "MANCH_F" description.
Basically, this should be "falling edge = logic 0", not "1" that applies
to "MANCH_R".
BTW, make the description complete by describing both rising/falling
edges as described in reference manuals.

Fixes: 6c82f947fc97 ("IIO: add DT bindings for stm32 DFSDM filter")

I'm feeling conservative today so will be wanting a devicetree
maintainer ack for this one..

Applied to the togreg branch of iio.git and pushed out as testing.
