iommu/vt-d: Populate debugfs if IOMMUs are detected [ Upstream commit 1da8347d8505c137fb07ff06bbcd3f2bf37409bc ] Currently, the intel iommu debugfs directory(/sys/kernel/debug/iommu/intel) gets populated only when DMA remapping is enabled (dmar_disabled = 0) irrespective of whether interrupt remapping is enabled or not. Instead, populate the intel iommu debugfs directory if any IOMMUs are detected.
