usb: patches for v4.3 merge window

New support for Allwinne SoC on the MUSB driver has been added to the list of
glue layers. MUSB also got support for building all DMA engines in one binary;
this will be great for distros.

DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on
tracing to debug DWC3. There was also a fix for memory corruption with EP0 when
maxpacket size transfers are > 512 bytes.

Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are
now required to set these flags up when adding endpoints to the framework.

Other than these, we have the usual set of miscelaneous cleanups and minor
fixes.

Allwinner sun4i A10 musb DRC/OTG controller

-------------------------------------------



Required properties:

 - compatible      : "allwinner,sun4i-a10-musb", "allwinner,sun6i-a31-musb"

                     or "allwinner,sun8i-a33-musb"

 - reg             : mmio address range of the musb controller

 - clocks          : clock specifier for the musb controller ahb gate clock

 - reset           : reset specifier for the ahb reset (A31 and newer only)

 - interrupts      : interrupt to which the musb controller is connected

 - interrupt-names : must be "mc"

 - phys            : phy specifier for the otg phy

 - phy-names       : must be "usb"

 - dr_mode         : Dual-Role mode must be "host" or "otg"

 - extcon          : extcon specifier for the otg phy



Example:



	usb_otg: usb@01c13000 {

		compatible = "allwinner,sun4i-a10-musb";

		reg = <0x01c13000 0x0400>;

		interrupts = <38>;

		interrupt-names = "mc";

		phys = <&usbphy 0>;

		phy-names = "usb";

		extcon = <&usbphy 0>;

		status = "disabled";
