soc: qcom: core_ctl: Add a tracing function
The core control module requires tracing capability. Export a function that will allow new events to be added in an extensible fashion without a compile-time dependency. Change-Id: I807d1ec4a104d8289441512b61e5e26df291525b Signed-off-by: Vikram Mulukutla <markivx@codeaurora.org>
