kernel-doc: add support for ____cacheline_aligned_in_smp attribute
Subroutine dump_struct uses type attributes to check if the struct syntax is valid. Then, it removes all attributes before using it for output. `____cacheline_aligned_in_smp` is an attribute that is not included in both steps. Add it, since it is used by kernel structs.
