I knew this was going to bit tricky. I can change all the places where I
am touching the code to generic names(change from intel_rdt to "resctrl").
Also lets change the "texts" which are visible to user to make it more
generic.

But "rdt" has been used generously in multiple files(like rdt_resource,
rdt_domain etc). Changing those definitions and functions will be messier.
I will not worry about it now. Thoughts?
