so it will break booting Windows on accelerators that do not support smm
by default starting from pc-i440fx-6.0 machine type.

It asserts in: 0xa5_FAILED_ACPI_TRANSITION_ACPI!ACPIEnableEnterACPIMode

Since smm is part of the guest ABI, can we just set use "!smm || smm-compat" whenever we use smm-compat right now?
