ata: Rework how flushing, sleeping, and power off interacts
* FLUSH_EXT is used if featureflag is set and we are using LBA48
(unconditionally used for CE-ATA on ipod6g)
* FLUSH is used if featureflag is set (ATA6+) or if device claims to be ATA5+
* Rename ata_disk_can_power_off() to ata_disk_can_sleep() as that is
what it actually tests for. Only use it to gate issuing the
STANDBY IMMEDIATE command.
* Restore behavior of ata_disk_is_active() to return 1 if drive is
"spinning" or powered up.
* Allow poweroff if drive claims PM support OR we are able to issue
FLUSH/FLUSH_EXT commands.
* Added ata_flush() to explicitly trigger a flush operation, and hook it
up to storage_flush() in the device shutdown path. (Flushes were
only previously used in the storage device power management path)
* After issuing all settings, re-issue IDENTIFY_DEVICE to make sure
it reflects everything we've enabled.
* Update manual section on Flash/SSD mods.
