Subject: xhci: add restart quirk for Intel Wildcatpoint PCH
From: Mathias Nyman <mathias.nyman@linux.intel.com>
commit 4c39135aa412d2f1381e43802523da110ca7855c upstream.
xHC in Wildcatpoint-LP PCH is similar to LynxPoint-LP and need the
same quirks to prevent machines from spurious restart while
shutting them down.
