sdiahci: fix staggered spinup wait loop, fix confusion
setting Asud in the cmd register is not needed, because
Apwr is (Asud|Apod) already. the problem really was that
the drive comes up with sstatus Spresent (001), so we never
spun it up because (p->sstatus & Sphylink) == 0 was never
met (Sphylink being a mask (011) overlaping Spresent bit).
the spinup wait loop has to run only for the staggered spinup
case (h->cap & Hss) and it should wait for the drive to be
detected by the phy, not just cold presence detect.
