iio: stm32-dfsdm: Treat flags as booleans
The "st,adc-alt-channel" and "st,filter0-sync" properties are
documented as boolean flags. The legacy parser read them as integer
cells, unlike the child-node parser which already checks only for
presence.
Use presence and boolean helpers so both parsers follow the binding and
the property type checker no longer reports the flags.
