crypto: caam - print debug messages at debug level
The CAAM driver used to put its debug messages inside #ifdef DEBUG and then prints the messages at KERN_ERR level. Replace this with proper functions printing at KERN_DEBUG level. The #ifdef DEBUG gets unnecessary when the right functions are used. This replaces: - print_hex_dump(KERN_ERR ...) inside #ifdef DEBUG with print_hex_dump_debug(...) - dev_err() inside #ifdef DEBUG with dev_dbg() - printk(KERN_ERR ...) inside #ifdef DEBUG with dev_dbg() Some parts of the driver use these functions already, so it is only consequent to use the debug function consistently.
