USB: changes for v4.11 

Here's the big pull request for the Gadget
 API. Again the majority of changes sit in dwc2
 driver. Most important changes contain a workaround
 for GOTGCTL being wrong, a sleep-inside-spinlock fix
 and the big series of cleanups on dwc2.
 
 One important thing on dwc3 is that we don't anymore
 need gadget drivers to cope with unaligned OUT
 transfers for us. We have support for appending one
 extra chained TRB to align transfer ourselves.
 
 Apart from these, the usual set of typos,
 non-critical fixes, etc.

USBA is the integrated high-speed USB Device controller on
the AT32AP700x, some AT91SAM9 and AT91CAP9 processors from Atmel.
The fifo_mode parameter is used to select endpoint allocation mode.
fifo_mode = 0 is used to let the driver autoconfigure the endpoints.
In this case 2 banks are allocated for isochronous endpoints and
only one bank is allocated for the rest of the endpoints.
fifo_mode = 1 is a generic maximum fifo size (1024 bytes) configuration
allowing the usage of ep1 - ep6
fifo_mode = 2 is a generic performance maximum fifo size (1024 bytes)
configuration allowing the usage of ep1 - ep3
fifo_mode = 3 is a balanced performance configuration allowing the
the usage of ep1 - ep8
