ACPICA: Executer: Add back pointing reference of method operand
ACPICA commit 9dcd124e914e87495fbd1786d9484b962e0823e0
This patch adds back pointing reference of the namespace node for a method
operand. The namespace node then can be used in
acpi_ds_terminate_control_method() to obtain method full path to be used by
tracing facilities. Lv Zheng.
