[Qemu-devel] [PATCH v4 02/14] memory-device: introduce separate config option

[David Hildenbrand <david@redhat.com>]

Some architectures might support memory devices, while they don't
support DIMM/NVDIMM. So let's
- Rename CONFIG_MEM_HOTPLUG to CONFIG_MEM_DEVICE
- Introduce CONFIG_DIMM and use it similarly to CONFIG NVDIMM

CONFIG_DIMM and CONFIG_NVDIMM require CONFIG_MEM_DEVICE.
