iio: add the IIO backend framework
This is a Framework to handle complex IIO aggregate devices.
The typical architecture is to have one device as the frontend device which
can be "linked" against one or multiple backend devices. All the IIO and
userspace interface is expected to be registers/managed by the frontend
device which will callback into the backends when needed (to get/set
some configuration that it does not directly control).
The basic framework interface is pretty simple:
- Backends should register themselves with @devm_iio_backend_register()
- Frontend devices should get backends with @devm_iio_backend_get()
