    It is better to use unified ASL path name to interact with the developers.
    
    There are following acpi_ns_build_normalized_pathname() users invoking it for
    debugging purposes (acpiexec test results are attached):
    
     1. acpi_ut_display_init_pathname (acpi_ns_handle_to_pathname):
         ---------------------------------------------
          Initializing Region        \_SB.H_EC.ECF2
         ---------------------------------------------
     2. acpi_ns_print_node_pathname (acpi_ns_handle_to_pathname):
         ---------------------------------------------
         - ex \_SB.H_EC._STA
         Evaluating \_SB.H_EC._STA
         ---------------------------------------------
     3. acpi_ds_print_node_pathname (acpi_ns_handle_to_pathname):
         ---------------------------------------------
         - level 211b console
         - execute \M1
         ...
         **** Exception AE_AML_UNINITIALIZED_ARG during execution of method [\M1] (Node 009CB6B8)
         ---------------------------------------------
     4. acpi_ex_dump_reference_obj (acpi_ns_handle_to_pathname):
         ---------------------------------------------
         - dump \_TZ.FAN4._PR0
         ...
         [00] 00835E98 [Object Reference] Type [Named Object] 05 00828878 \_TZ.FN04
         ---------------------------------------------
     5. acpi_db_bus_walk (acpi_ns_handle_to_pathname):
         ---------------------------------------------
         - businfo

         ...
         ---------------------------------------------
     6. acpi_db_walk_and_match_name (acpi_ns_handle_to_pathname):
         ---------------------------------------------
         - find _PR0
                           \_TZ.FAN4._PR0 Package      002D8DF8 01 Elements 01
         ---------------------------------------------
     7. acpi_db_walk_for_specific_objects (acpi_ns_handle_to_pathname):
         ---------------------------------------------
         - methods
         ...
                           \_SB.PCI0._PRT Method       0026D918 01 Args 0 Len 0005 Aml 0026B199
         ...
         ---------------------------------------------
     8. acpi_db_decode_and_dispaly_object (acpi_get_name):
         ---------------------------------------------
         - gpes
         Block 0 - Info 003AC7B0  device_node 003A0E08 [\_GPE] - FADT-defined GPE block
         ...
         ---------------------------------------------
     9. acpi_db_display_gpes (acpi_get_name):
         ---------------------------------------------
         - dump \_GPE
         Object (003A0E08) Pathname:  \_GPE
         ---------------------------------------------
     10.ae_miscellaneous_tests (acpi_get_name):
         No output available
    
    This patch cleans up all of the above usages. ACPICA BZ 1178, Lv Zheng.
    
    Linux kernel's ACPICA debugging messages may also be changed.
