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.
