ACPICA: Debugger: Cleanup debugging outputs to dump name path without…

… trailing underscores

ACPICA commit 51a49c2fb4a73f302a6df2b8ddc1350dd261684d

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
     \_SB.PCI0                        Type 6
     ...
     ---------------------------------------------
 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.
