if DIMMs with different size/alignment are interleaved
in creation order, it could lead to hotplug-memory
container fragmentation and following inability to use
all RAM upto maxmem.
For example:
-m 4G,slots=3,maxmem=7G
-object memory-backend-file,id=mem-1,size=256M,mem-path=/pagesize-2MB
-device pc-dimm,id=mem1,memdev=mem-1
-object memory-backend-file,id=mem-2,size=1G,mem-path=/pagesize-1GB
-device pc-dimm,id=mem2,memdev=mem-2
-object memory-backend-file,id=mem-3,size=256M,mem-path=/pagesize-2MB
-device pc-dimm,id=mem3,memdev=mem-3
fragments hotplug-memory container and doesn't allow
to use 1GB hugepage backend to consume remainig 1Gb.
To ease managment factor count in max 1Gb alignment for
each memory slot when sizing hotplug-memory region so
that regadless of fragmentaion it would be possible to
add max aligned DIMM.
