David Hildenbrand a89107c047 Documentation: sysfs/memory: clarify some memory block device properties 
In commit 53cdc1cb29 ("drivers/base/memory.c: indicate all memory blocks
as removable") we changed the output of the "removable" property of memory
devices to return "1" if and only if the kernel supports memory offlining.

Let's update documentation, stating that the interface is legacy.  Also
update documentation of the "state" property and "valid_zones" properties.
