Move the resource allocation from the ata_*_probe section to the ata_*_attach
section. This prevents a boot crash on nearly all iMacs and PowerMacs/Books.
The allocation in the probe section was working before because ata_probe was
returning 0 which did not invoke a second DEVICE_PROBE. Now it returns
a BUS_PROBE_DEFAULT which can invoke a second DEVICE_PROBE which results in
a "failed to reserve resource" exit.
