tee: optee: log message if dynamic shm is enabled
When dynamic shared memory support is enabled in the OP-TEE Trusted OS, it doesn't mean that the driver supports it, which can confuse users during debugging. Log a message when dynamic shared memory is enabled in the driver, to let users know for sure.
