Support CCI PMU in perf

CCI400 has a set of counters that can be used to profile different
transations at CCI master and slave interfaces. These counters can
observe different kinds of transations passing through the CCI and
provide a system-level view of activity.

This patch adds support for CCI PMU by extending the existing CCI
driver.
