* STAR 9001346572: This issue affects DWC_usb31 versions 1.80a and
* prior. When an active endpoint not currently cached in the host
* controller is chosen to be cached to the same index as an endpoint
* receiving NAKs, the endpoint receiving NAKs enters continuous
* retry mode. This prevents it from being evicted from the host
* controller cache, blocking the new endpoint from being cached and
* serviced.
*
* To resolve this, for controller versions 1.70a and 1.80a, set the
* GUCTL3 bit[16] (USB2.0 Internal Retry Disable) to 1. This bit
* disables the USB2.0 internal retry feature. The GUCTL3[16] register
* function is available only from version 1.70a.
