James Morse 1458c4f053 arm_mpam: resctrl: Add support for csu counters ... resctrl exposes a counter via a file named llc_occupancy. This isn't really a counter as its value goes up and down, this is a snapshot of the cache storage usage monitor. Add some picking code which will only find an L3. The resctrl counter file is called llc_occupancy but we don't check it is the last one as it is already identified as L3.
