Entries only show up in the schemata file for resources that are "alloc_capable".
So you should be able to make as many rdt_hw_resource structures as you
need that are "mon_capable", but not "alloc_capable" ... though making more
than one such resource may explore untested areas of the code since there
has historically only been one mon_capable resource. It looks like the resource
id from the "rid" field is passed through to the "show" functions for MBM and CQM.

This patch series splits the one resource that is marked as both mon_capable
and alloc_capable into two. Maybe that's a useful cleanup, but maybe not a
requirement for what you need.
