powerpc/powernv: Add IMC OPAL APIs
In-Memory Collection (IMC) counters are performance monitoring
infrastructure. These counters need special sequence of SCOMs to
init/start/stop which is handled by OPAL. And OPAL provides three APIs
to init and control these IMC engines.
OPAL API documentation:
https://github.com/open-power/skiboot/blob/master/doc/opal-api/opal-imc-counters.rst
Patch updates the kernel side powernv platform code to support the new
OPAL APIs
