David Hildenbrand 361469d853 virtio-mem: support CONFIG_PROC_VMCORE_DEVICE_RAM ...

Let's implement the get_device_ram() vmcore callback, so architectures
that select NEED_PROC_VMCORE_NEED_DEVICE_RAM, like s390 soon, can include
that memory in a crash dump.

Merge ranges, and process ranges that might contain a mixture of plugged
and unplugged, to reduce the total number of ranges.
