fs/resctrl: Make event details accessible to functions when reading events
Reading monitoring event data from MMIO requires more context than the event id
to be able to read the correct memory location. struct mon_evt is the appropriate
place for this event specific context.
Prepare for addition of extra fields to struct mon_evt by changing the calling
conventions to pass a pointer to the mon_evt structure instead of just the
event id.
