crypto: qat - make state machine functions static
The state machine functions adf_dev_init(), adf_dev_start(), adf_dev_stop() adf_dev_shutdown() and adf_dev_shutdown_cache_cfg() are only used internally within adf_init.c. Do not export these functions and make them static as state transitions are now performed using the safe function adf_dev_up() and adf_dev_down(). This commit does not implement any functional change.
