ACPICA: Fix to allow region arguments to reference other scopes
Allow referenced objects to be in a different scope.

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).
