    ahci: implement aggressive SATA device sleep support

    Device Sleep is a feature as described in AHCI 1.3.1 Technical Proposal.
    This feature enables an HBA and SATA storage device to enter the DevSleep
    interface state, enabling lower power SATA-based systems.

    Aggressive Device Sleep enables the HBA to assert the DEVSLP signal as
    soon as there are no commands outstanding to the device and the port
    specific Device Sleep idle timer has expired. This enables autonomous
    entry into the DevSleep interface state without waiting for software
    in power sensitive systems.

    This patch enables Aggressive Device Sleep only if both host controller
    and device support it.

    Tested on AMD reference board together with Device Sleep supported device
    sample.

I can confirm patch works for me with
- HighPoint RocketRAID 2720
and 
- LSI Logic / Symbios Logic SAS2008 (Falcon)) using mpt2sas
as well on 3.7.1.
Thanks!

Happy New Year!
Glad I found this bug before starting to dissect, it fixed my OCZ-REVODRIVE3
X2!

I have 960GB PCIe OCZ-REVODRIVE3 X2 that also uses mvsas and was working fine
with 3.6.9, but started failing with 3.7.1 (internally it is 4x SandForce 2281)
with only two of the four drives being detected. This was in dmesg:

$ grep "\] ata[91]" 3.7.1-pf-r6-a.dmesg 
[    0.807680] ata1: DUMMY
[    9.006504] ata9.00: ATA-8: OCZ-REVODRIVE3 X2, 2.22, max UDMA/133

[    9.363328] ata11.00: ATA-8: OCZ-REVODRIVE3 X2, 2.22, max UDMA/133
[    9.363334] ata11.00: 468862128 sectors, multi 16: LBA48 NCQ (depth 31/32)
[    9.363860] ata11.00: failed to get Identify Device Data, Emask 0x1
[    9.373757] ata11.00: failed to get Identify Device Data, Emask 0x1
[    9.373765] ata11.00: configured for UDMA/133
[    9.546921] ata12.00: both IDENTIFYs aborted, assuming NODEV

I applied the above patch (id=89551) to 3.7.1 and it started working again. I
hope it can be merged in 3.8.

Let me know if any more testing is needed.
