This patch renames ata_dev_present() to ata_dev_enabled() and adds

present but disabled from not-present state. This disctinction is
necessary when configuring transfer mode because device selection
timing must not be violated even if a device fails to configure.

Tangent thought: perhaps instead of ata_dev_present() you could
implement its antonym, ata_dev_absent(). It seems like a lot of the
constructs are "!dev_present()" anyway.
Interesting. I'll bite that. :)
