Rob Bradford 642b890b0f vm-virtio: mmio: Enable reporting of SHM regions via config fields
The details of the SHM regions or the lack of, which is used by
virtio-fs DAX, is communicated through configuration fields on the
virtio-mmio memory region. Implement the necessary fields to return the
SHM entries and in particular return a length of (u64)-1 which is used
by the kernel to indicate there are no SHM regions.
