hw/acpi/vmgenid: prevent device realization on pre-2.5 machine types
The WRITE_POINTER linker/loader command that underlies VMGENID depends on
commit baf2d5bfbac0 ("fw-cfg: support writeable blobs", 2017-01-12), which
in turn depends on fw_cfg DMA.
DMA for fw_cfg is enabled in 2.5+ machine types only (see commit
e6915b5f3a87, "fw_cfg: unbreak migration compatibility for 2.4 and earlier
machines", 2016-02-18).
