[PATCH] ACPICA: scope acpi_ex_trace_point() to ACPI_DEBUG_OUTPUT

[Pengpeng Hou]

In current linux.git (1954c4f01220), acpi_ex_trace_point() is
defined and declared unconditionally. However, its only in-tree caller
is within the debug tracing path in drivers/acpi/acpica/utdebug.c,
which is guarded by #ifdef ACPI_DEBUG_OUTPUT.

Match the internal declaration and definition to that scope by wrapping
them in #ifdef ACPI_DEBUG_OUTPUT. This fixes the debug-scope mismatch
and avoids including tracing logic when ACPI debug output is disabled.
