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

[Jacob Pan]

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.
