parisc: sba_iommu: Remove dead DEBUG_DMB_TRAP code
DEBUG_DMB_TRAP is unconditionally undefined, so the guarded
declarations and calls can never be built. The declared iterate_pages()
and set_data_memory_break() functions also have no definitions in the
tree; removing the #undef would therefore leave unresolved references.
Remove the unused option and its guarded code.
