[PATCH] tools: docs: memory-model: fix references for some files

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

- The sysfs.txt file was converted to ReST and renamed;
- The control-dependencies.txt is not at
  Documentation/control-dependencies.txt. As it is at the
  same dir as the README file, which mentions it, just
  remove Documentation/.

With that, ./scripts/documentation-file-ref-check script
is now happy again for files under tools/.
