hw/i386/pc: Remove PC_MACHINE_DEVMEM_REGION_SIZE

There are no remaining users in the tree. Libvirt never used that
property and a quick internet search revealed no other users.

Further, we renamed that property already in commit f2ffbe2b7dd0
("pc: rename "hotplug memory" terminology to "device memory"") without
anybody complaining.

So let's just get rid of it.
