perf/arm-cmn: Ensure port and device id bits are set properly

[ Upstream commit dfdf714fed559c09021df1d2a4bb64c0ad5f53bc ]

The portid_bits and deviceid_bits were set only for XP type nodes in
the arm_cmn_discover() and it confused other nodes to find XP nodes.
Copy the both bits from the XP nodes directly when it sets up a new
node.

Fixes: e79634b53e39 ("perf/arm-cmn: Refactor node ID handling. Again.")
