ATA: Increase delay to power-off when device doesn't support ATA SLEEP
The storage subsystem aggressively issues SLEEPNOW events when idle
and power off happened a fixed 2s later. This turns out to not be
enough time for FC1307A (eg iFlash) adapters to flush outstanding writes.
So, when we detect a lack of PM support, increase the poweroff delay to
5 seconds to compensate for not being able to issue the ATA SLEEP command.
Hopefully this is enough time. If not, we will have to re-disable PM
entirely when we detect these popular adapters. Thankfully that is now
just an #ifdef away.
