Kontron 986LCD-M update
- run ACPI code through preprocessor so we get the same values
as the C code
- fix PCIe x16 slot
- fix ICH7 Azalia/HDA driver
- SMI/GNVS update security fix (only allow struct pointer update once)
- ACPI updates
- IDE driver fixes
- add cmos options for disabling onboard ethernet and controlling system fan
