Before pushing on to more significant features a few unrelated patches
doing tidying up + one to avoid people setting the memory backend both
for a CXL type 3 device and as normal RAM in an attempt to get SRAT to
cover it correctly.  We've had multiple 'bug' reports from this and if
nothing else I'd like to stop getting those!

Based on master + the two DCD series Michael Tsirkin has queued.

Based-on: [PATCH v8 00/14] Enabling DCD emulation support in Qemu

I'll send a v2 that replaces the unused cfmw_list with the fix
that makes us of it to avoid a crash.
