usb: changes for v4.16 merge window

Not many changes here, the most important being an improvement for TI's
AM57xx and DRA7xx devices which allows them to disable a metastability
workaround in situations where we know what's going on.

Other than that, we have a set of changes on Renesas UDC to make the
code a little easier to read and maintain while also better supporting
extcon framework.

The u_serial adaptation layer learned to use kfifo instead of cooking
its own FIFO implementation.

DWC3 learned to decode a few more USB requests on the trace output.

Merge 4.15-rc4 into usb-next

2017-12-18T08:08:05+00:00

We want the USB fixes in here as well.

usb: dwc3: Allow disabling of metastability workaround

2017-12-11T10:36:53+00:00

Some platforms (e.g. TI's DRA7 USB2 instance) have more trouble
with the metastability workaround as it supports only
a High-Speed PHY and the PHY can enter into an Erratic state [1]
when the controller is set in SuperSpeed mode as part of
the metastability workaround.

This causes upto 2 seconds delay in enumeration on DRA7's USB2
instance in gadget mode.

If these platforms can be better off without the workaround,
provide a device tree property to suggest that so the workaround
is avoided.
