x86/resctrl: Add write option to "mba_MBps_event" file
The "mba_MBps" mount option provides an alternate method to control memory
bandwidth. Instead of specifying allowable bandwidth as a percentage of
maximum possible, the user provides a MiB/s limit value.
There is a file in each CTRL_MON group directory that shows the event
currently in use.
Allow writing that file to choose a different event.
A user can choose any of the memory bandwidth monitoring events listed in
/sys/fs/resctrl/info/L3_mon/mon_features independently for each CTRL_MON group
by writing to each of the "mba_MBps_event" files.
