usb: gadget: Add UDC driver for Aeroflex Gaisler GRUSBDC

USB Peripheral Controller driver for Aeroflex Gaisler GRUSBDC.

The GRUSBDC USB Device Controller core is available in the GRLIB VHDL

IP core library.

Note: In the ordinary environment for the core, a Leon SPARC system,

these properties are built from information in the AMBA plug&play.

Required properties:

- name : Should be "GAISLER_USBDC" or "01_021"

- reg : Address and length of the register set for the device

- interrupts : Interrupt numbers for this device

Optional properties:

- epobufsizes : An array of buffer sizes for OUT endpoints. If the property is

	not present, or for endpoints outside of the array, 1024 is assumed by

	the driver.

- epibufsizes : An array of buffer sizes for IN endpoints. If the property is

	not present, or for endpoints outside of the array, 1024 is assumed by

	the driver.

For further information look in the documentation for the GLIB IP core library:

http://www.gaisler.com/products/grlib/grip.pdf

	   Say "y" to link the driver statically, or "m" to build a

	   dynamically linked module called "fotg210_udc".
