x86/intel_rdt: Add basic resctrl filesystem support
Use kernfs as basis for our user interface filesystem. This patch
supports mount/umount, and one mount parameter "cdp" to enable code/data
prioritization (though all we do at this point is ensure that the system
can support CDP). The file system is not populated yet in this patch.
[ tglx: Fixed up a few nits and added cdp handling in case of error ]
