usb: fixes for-v4.4-rc5

Hopefully final set of fixes for v4.4 release cycle.

There's a fix for a regression on dwc3 caused by recent changes to how
transfers are started. We're not pre-starting interrupt endpoints
anymore.

A NULL pointer dereference fix for the MSM phy driver.

The UVC gadget got a minor fix for permissions to its configfs
attributes and, finally, two fixes for MUSB. A fix for PM runtime when
MUSB returns EPROBE_DEFER and a fix to actually return an error in case
we can't initialize a DMA engine.
