[libata] minor fixes, new helpers
- in ata_dev_identify(), don't assume that all devices are either ATA or ATAPI. In the future, this code will see port multipliers and other devices. - make a debugging printk less verbose - add new helper ata_qc_reinit() - add new helper BPRINTK() and port flag ATA_FLAG_DEBUGMSG, for fine-grained debugging use.
