- remove non-PCI support, since all supported platforms with at_wini devices also have PCI support by now; - correspondingly, stop using information from the BIOS altogether; - limit each driver instance to one controller, to be in line with the general MINIX3 one-instance-per-controller driver model; this limits the number of disks per at_wini instance to four; - go through the controllers by the order of their occurrence in the PCI table, thus removing the exception for compatibility devices; - let the second at_wini instance shut down silently if there is only one IDE controller; - clean up some extra code we don't need anymore, and resolve some WARNS=5 level warnings. Overall, these changes should simplify automatic loading of the right disk drivers at boot time in the future. Change-Id: Ia64d08cfbeb9916abd68c9c2941baeb87d02a806
