Add retry to slave core wakeup path
We are still seeing some very intermittent errors in the slave
core wakeup path. It still seems like we may have a timing issue.
Until we figure out exactly what is going on, I am adding a retry
mechanism that should get the core to report in correctly. The
retry is done by issuing an additional doorbell message to the
core that didn't report in.
