superio/acpi: Make _CRS methods Serialized, eliminating IASL remarks

When compiling for the ASUS P8H61-M LX, IASL 20180531 emits the
following remark: "Control Method should be made Serialized (due to
creation of named objects within)". Making the appropriate methods
Serialized eliminates these remarks.
