James Morse 7168ae330e x86,fs/resctrl: Move the resctrl filesystem code to live in /fs/resctrl
Resctrl is a filesystem interface to hardware that provides cache
allocation policy and bandwidth control for groups of tasks or CPUs.

To support more than one architecture, resctrl needs to live in /fs/.

Move the code that is concerned with the filesystem interface to
/fs/resctrl.
