acpinames: Cleanup stubs by linking some utilities objects.
This patch tries to reduce stubs for acpinames by adding some utilities objects to link. By doing so, we have to create stubs for AcpiEvTerminate(). While definining ACPI_REDUCED_HARDWARED can eliminate such requirements permanently. Then we are able to delete some AcpiHwXXX() AcpiEvXXX() stubs from anstubs.c It also makes senses to link exsystem.o and exmutex.o because they've already been made no-op by underlying OSL. By doing so, we can reduce some AcpiExXXX() stubs. Linking utids.o and uteval.o can help to reduce lots of stubs. It's safe to do so as such functions are not invoked by acpinames. This is the minimal effort to removing stubs from acpinames. Lv Zheng. Signed-off-by: Lv Zheng <lv.zheng@intel.com>
