bus: arm-ccn: Provide required event arguments
[ Upstream commit 8f06c51fac1ca4104b8b64872f310e28186aea42 ]
Since 688d4dfcdd624192cbf03c08402e444d1d11f294 "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.
