mainboard/winnet/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).
