Subject: [RESEND PATCH] regmap: debugfs: emit a debug message when locking is disabled

We currently silently omit creating the debugfs entries when regmap
locking is disabled. Users may not be aware of the reason for which
regmap files don't show up in debugfs. Add a dev_dbg() message
explaining that.

As discussed in private: this patch seems to have been lost, so resending.
