[Linux-nvdimm] [PATCH 1A] pmem: Add prints at pmem_probe/remove

Add small prints at creation/remove of pmem devices. So we can see in dmesg logs when users loaded/unloaded the pmem driver and what devices were created. The prints will look like this: Printed by e820 on load: [ +0.000000] user: [mem 0x0000000100000000-0x000000015fffffff] persistent (type 12) [ +0.000000] user: [mem 0x0000000160000000-0x00000001dfffffff] persistent (type 12) ...
