[ Upstream commit 8f06c51f ]

Since 688d4dfc "perf tools: Support
parsing parameterized events" the perf userspace tools understands
"argument=?" syntax in the events file, making sure that required
arguments are provided by the user and not defaulting to 0, causing
confusion.

This patch adds the required arguments lists for CCN events.
