thunderbolt: Increase timeout for Configuration Ready bit
After setting the Configuration Valid bit (ROUTER_CS_5.CV), the USB4
Connection Manager guide specifies a 500 ms timeout for the router to
set the Configuration Ready bit (ROUTER_CS_6.CR). The current timeout
is shorter than specified. While there, fix the kernel-doc typo.
Increase the timeout to match the CM guide recommendation.
