[PATCH v4 15/22] iommu/config: add build dependency for dmar

Intel VT-d interrupts come from both IRQ remapping and DMA remapping. In order to report non-recoverable faults back to device driver, we need to have access to IOMMU fault reporting APIs. This patch adds build depenency to DMAR code where fault IRQ handlers can selectively report faults.
