``phys_device`` read-only: legacy interface only ever used on s390x to
expose the covered storage increment.
-``removable`` read-only: contains an integer value indicating
- whether the memory block is removable or not
- removable. A value of 1 indicates that the memory
- block is removable and a value of 0 indicates that
- it is not removable. A memory block is removable only if
- every section in the block is removable.
-``valid_zones`` read-only: designed to show which zones this memory block
- can be onlined to.
+``removable`` read-only: legacy interface that indicated whether a memory
