Subject: [PATCH v2 21/27] coresight: Convert driver messages to dev_dbg
Convert component enable/disable messages from dev_info to dev_dbg.
This is required to prevent LOCKDEP splats when operating in perf
mode where we could be called with locks held to enable a coresight
path. If someone wants to really see the messages, they can always
enable it at runtime via dynamic_debug.
