Xiao Guangrong doesn't have enough time to actively review or contribute
to our NVDIMM implementation. Let's dissolve the "NVDIMM" section, moving
relevant ACPI parts to "ACPI/SMBIOS" and moving memory device stuff into a
new "Memory devices" section. Make that new section cover other memory
device stuff as well.
We can now drop the "hw/mem/*" rule from "ACPI/SMBIOS". Note that
hw/acpi/nvdimm.c is already covered by "ACPI/SMBIOS".
The following files in hw/mem don't fall into the TYPE_MEMPORY_DEVICE
category:
* hw/mem/cxl_type3.c is CXL specific and belongs to "Compute Express Link"
* hw/mem/sparse-mem.c is already covered by "Device Fuzzing"
* hw/mem/npcm7xx_mc.c is already covered by "Nuvoton NPCM7xx"
Thanks Xiao for your work on NVDIMM!

callback function and the update_arg parameter can be removed.
