4.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Felipe Balbi <balbi@xxxxxx>
[ Upstream commit 21939f003ad09355d9c975735750bb22aa37d8de ]
In case 'quirk-broken-port-ped' property is passed in via device property,
we should enable the corresponding BROKEN_PED quirk flag for XHCI core.
[rogerq@xxxxxx] Updated code from platform data to device property
and added DT binding.
