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). Cc: "Michael S.
