honor ACPI v4 FADT flags
- force use of physical APIC mode if indicated so (as we don't support
xAPIC cluster mode, the respective flag is taken to force physical
mode too)
- don't use MSI if indicated so (implies no IOMMU)
Both can be overridden on the command line, for the MSI case this at
once adds a new command line option allowing to turn off PCI MSI (IOMMU
and HPET are unaffected by this).
