From: Jonas Svennebring <jonas.svennebr...@gmail.com>
Add ccn-504 to dts, used by the ARM CCN driver.
The CCN driver support the CCN-504 bus and allows for
event counter readout through perf. See Documentation/arm/CCN.txt
Axxia AXM55xx supports XP nodes 0-10 and HFN nodes
3,5,7,8,13,15,17,18.
Note that the CCN perf driver utilizes the sysfs and therefore
requires the perf cli tool from kernel 3.14 or later.
