iio: industrialio-backend: support backend capabilities

2026-02-23T08:24:21+00:00

Not all backends support the full set of capabilities provided by the industrialio-backend framework. Capability bits can be used in frontends and backends for checking for a certain feature set, or if using related functions can be expected to fail. Capability bits should be set by a compatible backend and provided when registering the backend.
