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
...

5. acpi_db_bus_walk (acpi_ns_handle_to_pathname):

6. acpi_db_walk_and_match_name (acpi_ns_handle_to_pathname):
---------------------------------------------
- find _PR0

This patch cleans up all of the above usages. ACPICA BZ 1178, Lv Zheng.
Linux kernel's ACPICA debugging messages may also be changed.
