ACPICA: Fix Scope() op in module level code

commit 8df3fc98 upstream.

Some Panasonic Toughbooks create nodes in module level code.
Module level code is the executable AML code outside of control method,
for example, below AML code creates a node \_SB.PCI0.GFX0.DD02.CUBL

        If (\_OSI ("Windows 2006"))
        {
            Scope (\_SB.PCI0.GFX0.DD02)
            {
                Name (CUBL, Ones)
                ...
            }
        }

Scope() op does not actually create a new object, it refers to an
existing object(\_SB.PCI0.GFX0.DD02 in above example). However, for
Scope(), we want to indeed open a new scope, so the child nodes(CUBL in
above example) can be created correctly under it.
