MFC r356545:
Fix a XHCI driver issue with Intel's Gemini Lake SOC.

Do not configure any endpoint twice, but instead keep track of which
endpoints are configured on a per device basis, and use an evaluate
endpoint context command instead. When changing the configuration make
sure all endpoints get deconfigured and the configured endpoint mask
is reset.

This fixes an issue where an endpoint might stop working if there is
an error and the endpoint needs to be reconfigured as a part of the
error recovery mechanism in the FreeBSD USB stack.
