mainboard/neoware/g170: Add ACPI support
What is present is APIC and legacy interrupt routing and the soft-off sleep
state. Other sleep states are missing, so are the SuperIO devices.
Boots Linux with and without "noapic" and a Windows XP (installed with
factory BIOS, the installer reportedly requires legacy keyboard).
