usb: fixes for v4.3-rc3

Here's the second pull request for current -rc cycle.

A few fixes on dummy_hcd which have been around for
longer than they should be.

MUSB got a couple fixes, the most important of which
is a fix to DMA channel teardown on AM335x devices.

And DWC3 got a minor fix for when using RT-enabled
kernels.
