drivers/bus: Split Arm CCI driver
The arm-cci driver is really two entirely separate drivers; one for MCPM port control and the other for the performance monitors. Since they are already relatively self-contained, let's take the plunge and move the PMU parts out to drivers/perf where they belong these days. For non-MCPM systems this leaves a small dependency on the remaining "bus" stub for initial probing and discovery, but we end up with something that still fits the general pattern of its fellow system PMU drivers to ease future maintenance. Moving code to a new file also offers a perfect excuse to modernise the license/copyright headers and clean up some funky linewraps on the way.
