For sata port, only runtime pm needs to be taken care of;
For IDE port, only system pm needs to be taken care of.
Currently, we use PMSG_SUSPEND for both system suspend and runtime
suspend and PMSG_ON for both system resume and runtime resume.

Change this by using PMSG_AUTO_SUSPEND for runtime suspend and
PMSG_AUTO_RESUME for runtime resume.

The ata_acpi_set_state is modified accordingly. And the sata case and
pata case is seperated for easy understanding.

Can you rediff this on top of libata-dev.git #upstream?

Sure. Will send out when it's ready, thanks.
