If any software has interacted with the USB4 registers before the Linux
USB4 CM runs, it may have modified the plug events delay. It has been
observed that if this value too large, it's possible that hotplugged
devices will negotiate a fallback mode instead in Linux.

To prevent this, explicitly align the plug events delay with the USB4
spec value of 10ms.
