hw/i386/acpi-build: Rely on machine->device_memory when building SRAT
We're already looking at machine->device_memory when calling
build_srat_memory(), so let's simply avoid going via
PC_MACHINE_DEVMEM_REGION_SIZE to get the size and rely on
machine->device_memory directly.
Once machine->device_memory is set, we know that the size > 0. The code now
looks much more similar the hw/arm/virt-acpi-build.c variant.
