ACPI: create CONFIG_ACPI_DEBUG_FUNC_TRACE
Split ACPI_DEBUG into function trace enabled and not enabled.
Function trace is most of the ACPI_DEBUG costs, but is
not much of use for kernel ACPI debugging.
Size of kernel image increased on test compile:
+ 48k (Full ACPI_DEBUG)
+ 35k (ACPI_DEBUG with function trace compiled out)
Performance without function trace is also much better.
Also remove ACPI_LV_DEBUG_OBJECT from default debug level as
a lot vendors let Store (value, debug) in their code and this
might confuse users when it pops up in syslog.
