Virtio drivers should map the part of the range they need, not necessarily all of it. To this end, support mapping ranges within BAR on s390. Since multiple ranges can now be mapped within a BAR, we keep track of the number of mappings created, and only clear out the mapping for a BAR when this number reaches 0.
