Fix to ATA detect. Some devices seem to be comatose after reset
(return 0x00 status persistently). Send them identify to wake them up.
Flag value 0x10000 will enable probe messages for a channel/controller.
When UKC supports setting flags, this will be useful debugging
failing IDE detects without kernel recompiles.
