P0PHYCR isn't really readily dechipherable to "Port0 PHY Control".
Probably keeping the comment is better?  Also, constant names don't
necessarily have to be exactly the same as hardware manuals.  If
easier to understand and map back (via comment or whatever), using
more humanly-readable names is completely fine.  Also, maybe IMX_SATA_
is a bit too long for prefix?

Thanks.
