This patch set adds an extended usage of Feature ID for DFL. Previously the feature IDs defined are unique, no matter which feature type. But currently we want to extend its usage to have a per-type feature ID space. Patch 1 adds feature type checking before parse the irq info. Patch 2 adds description about the Feature ID. v4: - Fix the git commit from Hao's comments. - Split documentation into another patch. v3: - Remove "Fixes" in commit log with Hao's comment, this is a extension not a bug fix. v2: - add DFL Feature ID Registry in documentation.
