USB changes for 5.4-rc1

Here is the big set of USB patches for 5.4-rc1.
 
 Two major chunks of code are moving out of the tree and into the staging
 directory, uwb and wusb (wireless USB support), because there are no
 devices that actually use this protocol anymore, and what we have today
 probably doesn't work at all given that the maintainers left many many
 years ago.  So move it to staging where it will be removed in a few
 releases if no one screams.
 
 Other than that, lots of little things.  The usual gadget and xhci and
 usb serial driver updates, along with a bunch of sysfs file cleanups due
 to the driver core changes to support that.  Nothing really major, just
 constant forward progress.
 
 All of these have been in linux-next for a while with no reported
 issues.

USB GPIO Based Connection Detection
This is typically used to switch dual role mode from the USB ID pin connected
to an input GPIO, and also used to enable/disable device mode from the USB
Vbus pin connected to an input GPIO.
Required properties:
- compatible : should include "gpio-usb-b-connector" and "usb-b-connector".
- id-gpios, vbus-gpios : input gpios, either one of them must be present,
and both can be present as well.
see connector/usb-connector.txt
Optional properties:
- vbus-supply : can be present if needed when supports dual role mode.
see connector/usb-connector.txt
- Sub-nodes:
- port : can be present.
see graph.txt
Example:
&mtu3 {
connector {
compatible = "gpio-usb-b-connector", "usb-b-connector";
type = "micro";
id-gpios = <&pio 12 GPIO_ACTIVE_HIGH>;
vbus-supply = <&usb_p0_vbus>;
