dt-bindings: iio: adc: stm32-dfsdm: fix types, add missing pinctrl

Browse source

- 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.
