Just for preview. Please don't merge it.
Agree, I will fix it. Currently, I think only basic, logical channel can be merged. tee_svc_reader_get_name() and tee_svc_reader_get_prop() might be able to merge to tee_svc_reader_get_info(), but it's needed to introduce new data structure. Others is hard to merge because I put everything in the kernel, and user space only knows the "handle"
