Like sas_printk() did previously, SAS_DPRINTK() offers little value now that libsas logs already have the "sas" prefix through pr_fmt(fmt). So it can be dropped. However, after reviewing some logs in libsas, it is noticed that debug level is too low in many instances. So this change drops SAS_DPRINTK() and revises some logs to a more appropriate level. However many stay at debug level, although some are significantly promoted. We add -DDEBUG for compilation so that we keep the debug messages by default, as before. All the pre-existing checkpatch errors for spanning messages across multiple lines are untouched. Finally, all other references to printk() are removed and replaced with appropriate pr_xxx().
