qemu provides acpi and smbios tables via fw_cfg for many years
now. The builtin tables shipped by seabios are only used as
fallback for old qemu versions.
qemu is about to drop backward compatibility for old versions,
machine types for versions 1.4 to 1.7 are deprecated, which

Not needed any more now that ZoneHigh is expanded on demand.

When running out of memory get a chunk of memory from ZoneTmpHigh to
expand ZoneHigh. Drop simliar logic fro pmm code because it's not
needed ay more.
This fixes some scalability problems, for example with lots of vcpus,
where seabios runs out of memory due to large smbios/acpi tables.
