bus: arm-ccn: Provide required event arguments
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. Signed-off-by: Pawel Moll <pawel.moll@arm.com>
