asrock/e350m1: Serialize ACPI IDE methods to avoid races.

Fix the remark introduced in ACPICA version 20130517 pertaining to
    blocking threads within a methods. If another thread attempts to use the
    method to create the same (named) object twice a race condition will
    occur. ACPICA BZ 909.
