Subject: [RFC][PATCH 0/2] dwc2 fixes for HiKey

I wanted to send out two patches we're using on the dwc2
driver in order to make HiKey function.

The first is seemingly just a bug fix we ran into when
changing modes while the bus was auto-suspended.

The second is a little more interesting as it works around
a limitation of the the device to negotiate the usb speed
automatically.

I wanted to send these out for initial review and consideration.

Feedback would be greatly appreciated!

thanks
-john
