When Microsoft Hypervisor runs on Intel platforms it needs to know the
reserved regions to program devices correctly. There is no reason to
duplicate intel_iommu_get_resv_regions. Export it.

Why not using iommu_get_resv_regions()?

That calls into ops->get_resv_regions.

In this patch series, get_resv_regions is hv_iommu_resv_regions, which
wants to use intel_iommu_get_resv_regions when it detects the underlying
hardware platform is from Intel.
