Alexander Motin 72a61203fc Change the way how "not implemented" AHCI channels handled. Instead of
completely skipping them, create ahcich devices for them to allocate unit
numbers, but mark them as disabled to prevent driver probe and attach.

Last time some BIOSes tend to report unused channels as "not implemented".
This change makes ahcichX devices numbering consistent, independently of
connected disks. It makes per-channel driver hints usable and CAM devices
wiring possible on such systems.
