pata_artop: fix UDMA5 for AEC6280[R] and UDMA6 for AEC6880[R]
Maximum supported UDMA mode for AEC6280[R] is UDMA5 (not UDMA4) and for AEC6880[R] it is UDMA6 (not UDMA5): * Fix the problem by adding missing struct ata_port_info to artop_init_one(). * Use the right naming (s/626/628/). * Bump driver version. Fixes IDE->libata regression, problem was never present in IDE aec62xx driver.
