usb: fixes for v4.15-rc2

After a long time, we finally have a good solution for how to handle
OS descriptor on FFS. From now on we will force the Reserved field to
be 1 as mandated by the specification.

Apart from that, we have a couple other smaller fixes:

- FFS learned to not sleep in atomic context.
- UDC-core has a fix for the way we set a UDC's operating speed.
- Renesas USB3 has a fix for the maximum number of pipes supported
- Allow legacy drivers to be compiled without USB_ETH
- Fix some coccinelle warnings
