[PATCH 4/5] thunderbolt: Increase timeout to wait for Configuration Ready bit

[Gil Fine <gil.fine@linux.intel.com>]

After setting the Configuration Valid bit (ROUTER_CS_5.CV), the USB4
Connection Manager guide recommends waiting for the router to set the
Configuration Ready bit (ROUTER_CS_6.CR), with a timeout of 500 ms.

Increase the timeout to comply with the specification.

While there, fix the kernel-doc typo.
