ACPI: enable ACPI from command line
Previously the "acpi=off" in cmdline has disabled the ACPI for the guest kernel. With removing the "acpi=off", the ACPI will be enabled for the guest kernel by default. With acpi enabled, the SCI irq will be needed by the ACPI core driver. Register the SCI irq in MP table so that it can use IO-APIC routing. The reason to have "pci=noacpi" is that, in the current DSDT there is only suspend capability, so PCI scan still need to be done by the traditional way. BUG=chromium:1018674 TEST=Linux guest is able to boot up with the virtio devices functional. Also able to see the S1 capability from kernel dmesg.
