Subject: [PATCH 1/2] tools/dma: move dma_map_benchmark from selftests to tools/dma

dma_map_benchmark is a standalone developer tool rather than an
automated selftest.  It has no pass/fail criteria, expects manual
invocation, and is built as a normal userspace binary.Move it to
tools/dma/ and add a minimal, the original selftest.Makefile entry
is removed to avoid duplication.
