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)
...
Printed by modprobe pmem:
[ +0.003065] pmem pmem.0.auto: probe [0x0000000100000000:0x60000000]
[ +0.001816] pmem pmem.1.auto: probe [0x0000000160000000:0x80000000]
...
Printed by modprobe -r pmem:
[ +16.299145] pmem pmem.1.auto: remove
[ +0.011155] pmem pmem.0.auto: remove
