====================
irda: move it to drivers/staging so we can delete it

The IRDA code has long been obsolete and broken.  So, to keep people
from trying to use it, and to prevent people from having to maintain it,
let's move it to drivers/staging/ so that we can delete it entirely from
the kernel in a few releases.
