SVN rev 212359 on 2010-09-09 13:17:30Z by nwhitehorn
Fix a problem where device detection would work unreliably on Serverworks
K2 SATA controllers. The chip's status register must be read first, and
as a long, for other registers to be correctly updated after a command, and
this includes the command sequence in device detection as well as the
previously handled case after interrupts. While here, clean up some
previous hacks related to this controller.
