Nicolin Chen b391e41e53 backends/iommufd: Introduce iommufd_backend_viommu_mmap ...

Add a backend helper to mmap hardware MMIO regions exposed via iommufd for
a vIOMMU instance. This allows user space to access HW-accelerated MMIO
pages provided by the vIOMMU.

The caller is responsible for unmapping the returned region.
