No maintainers handling the code (so subsystem maintainers) are shown with
scripts/get_maintainers.pl on MPAM drivers in drivers/resctrl/.  It
seems that there is no dedicated subsystem for resctrl and existing
drivers went through ARM64 port maintainers, so make that explicit to
avoid patches being lost/ignored.

What's wrong with the current entry?

I explained in the commit msg:
"No maintainers handling the code (so subsystem maintainers)"

It does not list the maintainers picking up patches, so if you use
standard tools (like b4, patman or scripted get_maintainers), you will
never appear on To/Cc list (relying on git-fallback is wrong).

Of course maybe you will still get the patches with lei/korgalore, so up
to you.
