When the device port is in a low power state [U3/L2/Not Connected], accesses to usb device registers may take a long time. This could lead to potential core hang when the controller registers are accessed after the port is disabled by setting DEVDS field. Setting the fast register access bit ensures that the PHY clock is keeping up in active state.
Therefore, set fast access bit to ensure the accesses to device registers are quick even in low power states.
