[PATCH 2/5] [UPDATED] coresight: Convert pr_warn to dev_warn for obsolete bindings

[PATCH 2/5] [UPDATED] coresight: Convert pr_warn to dev_warn for obsolete bindings

[Suzuki K Poulose]

We warn the users of obsolete bindings in the DT for coresight replicator
and funnel drivers. However we use pr_warn_once() which doesn't give a clue
about which device it is bound to. Let us use dev_warn_once() to give the
context.

Changes since previous version:
 - Update replicator driver too.
