usb: fixes for v4.15-rc4
We have a few fixes on dwc3:
- one fix which only happens with some implementations where we need to
wait longer for some commands to finish.
- Another fix for high-bandwidth isochronous endpoint programming making
sure that we send the correct DATA tokens in the correct sequence
- A couple PM fixes on dwc3-of-simple
The other synopsys controller driver (dwc2) got a fix for FIFO size
programming.
Other than these, we have a couple Kconfig fixes making sure that
dependencies are properly setup.
