USB: fixes for v5.9-rc4

Hi,

Here's my second pull request for the current -rc cycle. Not much going on, I wonder where are all the bugs :-p

Nothing major here, simple fixes that have been around for some time. Let me know if you want me to change anything here.

Cheers

USB: fixes for v5.9-rc4

Support for Hikey 970 has been added on dwc3-of-simple; cdns3 learned that once the gadget is removed, its interrupt should be freed; dwc3 also got improvements to how we handle CLEAR_STALL requests.
