iio: adc: stm32-dfsdm: adopt generic channels bindings
Move to generic channels binding to ease new backend framework adoption
and prepare the convergence with MDF IP support on STM32MP2 SoC family.
Legacy binding:
DFSDM is an IIO channel consumer.
SD modulator is an IIO channels provider.
The channel phandles are provided in DT through io-channels property
and channel indexes through st,adc-channels property.
New binding:
DFSDM is an IIO channel provider.
The channel indexes are given by reg property in channel child node.
This new binding is intended to be used with SD modulator IIO backends.
It does not support SD modulator legacy IIO devices.
The st,adc-channels property presence is used to discriminate
between legacy and backend bindings.
The support of the DFSDM legacy channels and SD modulator IIO devices
is kept for backward compatibility.
