ENGR00172292 usb otg: enable dtds postpone free on mx6
We found this bug occurs again on mx6 when running
CTS with ADB over USB. The system will hang without
any log, and screen a little mess.
It's proved to be a known USB IP issue: USB controller
may access a wrong address for the dTD and then hang.
Re enable this workaround to avoid any system unstability.
