#     powerpc/perf: Unregister thread-imc if core-imc not supported
#     
#     Since thread-imc internally use the core-imc hardware infrastructure
#     and is depended on it, having thread-imc in the kernel in the
#     absence of core-imc is trivial. Patch disables thread-imc, if
#     core-imc is not registered.
