SVN rev 189166 on 2009-02-28 11:25:05Z by mav
Rework device probing by moving ata_getparam() call from ata_identify() to
drivers' probe routines. It allows not to sleep and so not drop Giant inside
ata_identify() critical section and so avoid crash if it reentered on
request timeout. Reentering of probe call checked inside of it.
Give device own knowledge about it's type (ata/atapi/atapicam). It is not
a good idea to ask channel status for device type inside ata_getparam().
Add softc memory deallocation on device destruction.
