usb: fixes for v3.6-rc4

Here's a rather big set of fixes for v3.6-rc4.

There are some fixes for bugs which have been pending for a long
time and only now were uncovered, like the musb and dwc3 patches.

We have some remaining fixes for the ep->desc patch series from
Ido, a fix for renesas DMA usage, IRQ check on musb's DMA and
an oops fix on musb Host implementation.

All patches have been pending on linux-usb for a long time and
shouldn't cause any further regressions.
