Jetway NF81-T56N-LF: Serialize ACPI method remarks to avoid race-conditions.

Fix the remark introduced in ACPICA version 20130517 that gives the
    following explanation:

If a thread blocks within the method for any reason, and another thread
            enters the method, the method will fail because an attempt will be
            made to create the same (named) object twice.

In this case, issue a remark that the method should be marked
            serialized. ACPICA BZ 909.

The toolchain remarks fixed by this are as follows:
