ACPICA: Update default space handlers.
This patch adds code that is already in ACPICA upstream, so applying it can help to reduce the source code differences between Linux and ACPICA upstream. This code fragment is only useful for ACPICA utilities and no functional changes to the Linux kernel should result from it.
