Subject: [PATCH] driver: of: overlay: demote message to warning

This warning message shows by default on the vast majority of overlays
applied. Despite the text identifying this as a warning it is marked
with the loglevel for error. At Cisco we filter the loglevels to only
show error messages. We end up seeing this message but it's not really
an error.

For this reason it makes sense to demote the message to the warning
loglevel.
