With the Trustzone based CDSP remoteproc driver these clocks are controlled elsewhere and as they are not enabled by anything in Linux the clock framework will turn them off during lateinit. This results in issues either to later start the CDSP, using the Trustzone interface, or if the CDSP is already running it will crash.
