[SeaBIOS] [PATCH 2/2] acpi: Set FORCE_APIC_CLUSTER_MODEL bit of FADT flags

[zhanghailiang]

If we start Windows 2008 R2 DataCenter with number of cpu less than 8,
The system will use APIC Flat Logical destination mode as default configuration,
Which has an upper limit of 8 CPUs.

The fault is that VM can not show all processors within Task Manager if
we hot-add cpus when the number of cpus in VM extends the limit of 8.

If we use cluster destination model, the problem will be solved.
