ACPICA: Revert "Parser: Fix for SuperName method invocation"
ACPICA commit eade8f78f2aa21e8eabc3380a5728db47273bcf1
Revert commit ae90fbf562d7 (ACPICA: Parser: Fix for SuperName method
invocation).
Support for method invocations as part of super_name will be
removed from the ACPI specification, since no AML interpreter
supports it.
Fixes: ae90fbf562d7 (ACPICA: Parser: Fix for SuperName method invocation)
