Trying to avoid making more work for the ARM folks as they split resctrl
into "file system" and "architecture specific" bits.
mba_mbps_default_event isn't architecture specific. The mba_MBps
feedback code could be implemented on any architecture that supports
both measurement and control of memory bandwidth.
