[RFC v3 13/25] intel_iommu: modify x-scalable-mode to be string option

2020-01-29 Thread Liu, Yi L
From: Liu Yi L Intel VT-d 3.0 introduces scalable mode, and it has a bunch of capabilities related to scalable mode translation, thus there are multiple combinations. While this vIOMMU implementation wants simplify it for user by providing typical combinations. User could config it by
