southbridge/intel: Move `i82801gx/acpi/platform.asl` to `common/acpi`
Commit 24813c14 (i945: Consolidate acpi/platform.asl) creates the file in the directory `src/southbridge/intel/i82801gx/acpi`. Devices with the southbridge `intel/i82801ix`, like the laptop Lenovo X200, use the exact same ASL code though. So share this in the directory `src/southbridge/intel/common/acpi`.
