xhci: Fix some regressions introduced in 3.14.

Hi Greg,

Here's four patches for 3.14.

One of them adds an xHCI host quirk, and the other three of them fix
regressions introduced in 3.14.  One regression causes USB 3.0 Link PM to
be enabled on all xHCI hosts (even those that may not support it), which
causes some USB 3.0 devices to not enumerate.  A second regression causes
some xHCI hosts that don't support 64-bit addressing to stop responding to
commands and die.

Note, these patches don't fix the recent usbfs regression that was caused
by commit 35773dac5f862cb1c82ea151eba3e2f6de51ec3e "usb: xhci: Link TRB
must not occur within a USB payload burst".  I'm waiting for those patches
to be tested.

Please pull usb-linus into usb-next, as I have feature patches that rely on
