[PATCH v2 23/26] docs: nios2: add it to the main Documentation body

[Mauro Carvalho Chehab <mchehab+samsung@xxxxxxxxxx>]

Rename and add the nios2 documentation to the documentation
body.

The nios2 document is already on an ReST compatible format.
All it needs is that the title of the document to be promoted
one level.
