I'm thinking that I could continue splitting things and break "struct rdt_resource" into
separate "ctrl" and "mon" structures. Then we'd have a clean split from top to bottom.

Doing that would get rid of the rdt_resources_all[] array. Replacing with individual
rdt_hw_ctrl_resource and rdt_hw_mon_resource declarations for each feature.

Features found on a system would be added to a list of ctrl or list of mon resources.
