iio: backend: add devm_iio_backend_get_by_index()
Add a new function to get an IIO backend by its index in the
io-backends device tree property. This is useful for multi-channel
devices that have multiple backends, where looking up by index is
more straightforward than using named backends.
Extract __devm_iio_backend_fwnode_get_by_index() from the existing
__devm_iio_backend_fwnode_get(), taking the index directly as a
parameter. The new public API devm_iio_backend_get_by_index() uses
the index to find the backend reference in the io-backends property,
avoiding the need for io-backend-names.
