[PATCH] Documentation: fix tty link

[Jiri Slaby]

The commit below causes the following warnings:
Documentation/driver-api/index.rst:14: WARNING: toctree contains reference to nonexisting document 'driver-api/tty'
Documentation/driver-api/tty/index.rst: WARNING: document isn't included in any toctree

This is because I omitted the "/index" part from the link. That part is
needed for directories and I was confused by the surrounding links which
are links to files. Fix it in this patch.
