[wwwdocs] Remove developer.intel.com link from readings.html

[Gerald Pfeifer]

Intel's web team had this now redirect to a general product page
(for hardware).  With such an approach, I don't want to link to
them directly any longer -- people can just google for whatever
the location of the day of manuals etc. may be.

Applied.
