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.
