xhci: Step 1 to fix usb-linus and usb-next.

Hi Greg,

This is the first of three steps to fix your usb-linus and usb-next
trees.  As I mentioned, commit 76d4c949cfa667255a74254c93ead1e963c76beb
"USB: handle LPM errors during device suspend correctly" was incorrectly
added to usb-next when it should have been added to usb-linus and marked
for stable.

Two port power off bug fixes touch the same code that patch touches, but
it's not easy to simply move commit 76d4c949 patch to usb-linus because
commit 11894b6bfcf7798a646d63347671469d07db32d8 "USB: refactor code for
enabling/disabling remote wakeup" also touched those code sections.

I propose a two step process to fix this:

1. Pull these four patches into usb-linus.

2. Revert commit 11894b6bfcf7798a646d63347671469d07db32d8 from usb-next.
   Merge usb-linus into usb-next, and resolve the conflicts.

I will be sending pull requests for these steps.

This pull request is step one, and contains the backported version of
commit 76d4c949cfa667255a74254c93ead1e963c76beb, the two port power off
fixes, and an unrelated xhci-plat bug fix.
