usb: dwc3: host: pass quirk-broken-port-ped property for known broken revisions
dwc3 revisions <=3.00a have a limitation where Port Disable command doesn't work. Set the quirk-broken-port-ped property for such controllers so XHCI core can do the necessary workaround. [rogerq@ti.com] Updated code from platform data to device property. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
