x86/intel_rdt: Make information files resource specific
Cache allocation and memory bandwidth allocation require different
information files in the resctrl/info directory, but the current
implementation does not allow to have files per resource.
Add the necessary fields to the resource struct and assign the files
dynamically depending on the resource type.
