[Skiboot] [RFC PATCH 2/4] ibm-fsp/firenze: uncore_init hook

[Madhavan Srinivasan]

Patch adds a init hook function in ibm-fsp/firence file
to initialize the Nest instrumentation. Reason for adding this
function is that, currently the Nest instrumentation
detection feature is under development and the code has been
tested only in IBM Tuleta boxes.
