Robin Murphy 54e85ee2b4 perf/arm-cmn: Fix port detection for CMN-700 ... [ Upstream commit 2ad91e44e6 ] When the "extra device ports" configuration was first added, the additional mxp_device_port_connect_info registers were added around the existing mxp_mesh_port_connect_info registers. What I missed about CMN-700 is that it shuffled them around to remove this discontinuity. As such, tweak the definitions and factor out a helper for reading these registers so we can deal with this discrepancy easily, which does at least allow nicely tidying up the callsites. With this we can then also do the nice thing and skip accesses completely rather than relying on RES0 behaviour where we know the extra registers aren't defined.
