Kconfig symbol ACPI_DEBUG_FUNC_TRACE was only used (through its
corresponding macro) in drivers/acpi/acpica/acmacros.h. That macro was
removed from that header in v3.8, with commit
86ff0e508f88eda6e479a897476026055831d2d8 ("ACPICA: Fix unmerged
acmacros.h divergences."). That commit did not explain why that macro
was removed. But it seems that ACPI_DEBUG_FUNC_TRACE can now be removed
too, as it is unused.
