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.
