    ACPICA: Fix to allow region arguments to reference other scopes

    Allow referenced objects to be in a different scope.

    http://www.acpica.org/bugzilla/show_bug.cgi?id=937

    ACPI Error: [RAMB] Namespace lookup failure, AE_NOT_FOUND
(20110112/psargs-359)
    ACPI Exception: AE_NOT_FOUND, Could not execute arguments for [RAMW]
(Region) (20110112/nsinit-349)

        Scope (_SB)
        {
            Name (RAMB, 0xDF5A1018)
            OperationRegion (\RAMW, SystemMemory, RAMB, 0x00010000)
        }

    For above ASL code, we need to save scope node(\_SB) to lookup
    the argument node(\_SB.RAMB).
