Subject: bus: arm-ccn: Fix node->XP config conversion
From: Pawel Moll <pawel.moll@xxxxxxx>
commit a18f8e97fe69195823d7fb5c68a8d6565f39db4b upstream.
Events defined as watchpoints on nodes must have their config values
converted so that they apply to the respective node's XP. The
function setting new values was using wrong mask for the "port" field,
resulting in corrupted value. Fixed now.
