xhci: Final patches for 3.13

Hi Greg,

Here's my pull request for usb-next and 3.13.  My xHCI tree is closed
after this point, since I won't be able to run my full tests while I'm in
Scotland.  After Kernel Summit, I'll be on vacation with access to email
from Oct 26th to Nov 6th.

Here's what's in this request:

 - Patches to fix USB 2.0 Link PM issues that cause USB 3.0 devices to not
   enumerate or misbehave when plugged into a USB 2.0 port.  Those are
   marked for stable.

 - A msec vs jiffies bug fix by xiao jin, which results in fairly harmless
   behavior, and thus isn't marked for stable.

 - Xenia's patches to refactor the xHCI command handling code, which makes
   it much more readable and consistent.

 - Misc cleanup patches, one by Sachin Kamat and three from Dan Williams.

Here's what's not in this request:

 - Dan's two patches to allow the xHCI host to use the "Windows" or "new"
   enumeration scheme.  I did not have time to test those, and I want to
   run them with as many USB devices as I can get a hold of.  That will
   have to wait for 3.14.

 - Xenia's patches to remove xhci_readl in favor of readl.  I'll queue
   those for 3.14 after I test them.

 - The xHCI streams update, UAS fixes, and usbfs streams support.  I'm not
   comfortable with changes and fixes to that patchset coming in this late.
   I would rather wait for 3.14 and be really sure the streams support is
   stable before we add new userspace API and remove CONFIG_BROKEN from the
   uas driver.

 - Julius' patch to clear the port reset bit on hub resume that came in
   a couple days ago.  It looks harmless, but I would rather take the time
   to test and queue it for usb-linus and the stable trees once 3.13-rc1
   is out.
