powercap: intel_rapl: Support per Interface rapl_defaults
rapl_defaults is Interface specific.
Although current MSR and MMIO Interface share the same rapl_defaults,
new Interface like TPMI need its own rapl_defaults callbacks.
Save the rapl_defaults information in the Interface private structure.
No functional change.
