alpha: make IOMMU respect the segment boundary limits
This patch makes the IOMMU code not allocate a memory area spanning LLD's
segment boundary.
is_span_boundary() judges whether a memory area spans LLD's segment boundary.
If iommu_arena_find_pages() finds such a area, it tries to find the next
available memory area.
