From: Andi Shyti <andi.shyti@xxxxxxxxx>
Replace the legacy for_each_engine* defines with the ones
implemented in the gem_engine_topology library.
Use whenever possible gem_engine_can_store_dword() that checks
class instead of flags.
Now the __for_each_engine_class_instance and
for_each_engine_class_instance are unused, remove them.
