x86/resctrl: Rename and move rdt files to a separate directory
New generation of AMD processors add support for RDT (or QOS) features.
Together, these features will be called RESCTRL. With more than one
vendors supporting these features, it seems more appropriate to rename
these files.
Create a new directory with the name 'resctrl' and move all the
intel_rdt files to the new directory. This way all the resctrl related
code resides inside one directory.
[ bp: Add SPDX identifier to the Makefile ]
