Old igd.asl had inconsistent addresses (between _DOD and actual device) and ghost devices. Any of those is enough to make brightness on windows fail and make igd.asl out-of-ACPI-spec. Also old code favoured ridiculous copying of the same thing 6 times per chipset. Leave only hooking up and chipset-specific part in chipset directory. Move NVS handling and ACPI-spec parts to a common file.
