Note that n is the default, we can drop this.

This part of the Makefile can be tricky to read. We should be able to use the normal formation of 'obj-$(CONFIG_GIC_V3_ITS)' in this spot in the file as we don't have other difficult to express concisely in make constraints around.
Other than that, please make sure the code is checkpatch clean, I don't have any commentary on the implementation itself but I gather it's tested on your end. Thanks!
