fsl/usb: Workarourd for USB erratum-A005697

As per USB specification, in the Suspend state, the status bit does
not change until the port is suspended. However, there may be a delay
in suspending a port if there is a transaction currently in progress
on the bus.

In the USBDR controller, the PORTSCx[SUSP] bit changes immediately when
the application sets it and not when the port is actually suspended

Workaround for this issue involves waiting for a minimum of 10ms to
allow the controller to go into SUSPEND state before proceeding ahead
