Documentation: Sandybridge RAM init: Fix links for Sphinx/recommonmark

Add a dash before the links to other files to mark those files as
subpages, and avoid the following error:

  reading sources... [ 33%] Intel/NativeRaminit/Sandybridge
  Exception occurred:
    File "/usr/lib/python2.7/dist-packages/recommonmark/states.py", line 134, in run_role
      content=content)
  TypeError: 'NoneType' object is not callable

While at it, also spell these filenames correctly: Only
SandyBridge_registers.md is spelled in camel-case.
