Adapt the usb-compat.h to uBoot.
Use #ifndef __UBOOT__ for code that is not applicable to uBoot.
Use #ifdef __UBOOT__ to add code that is uBoot specific.
Create linux-compat.h - Linux kernel compatibility definitions that do not
exist in the uBoot. Moved the compatibility definitions from
lin_gadget_compat.h
to this file as well.
Create usb-mod-devicetable.h - Is a partial back port of mod_devicetable.h in
the linux
kernel only taking the portion needed for USB
Already existing header files were modified to pick up the new header files.
Currently musb will not compile.

+ * against new devices. Any field except for driver_info may be used,
+ * although some only make sense in conjunction with other fields.
+ * This is usually set by a USB_DEVICE_*() macro, which sets all
+ * other fields in this structure except for driver_info.
+ * @idVendor: USB vendor ID for a device; numbers are assigned
+ * by the USB forum to its members.
+ * @idProduct: Vendor-assigned product ID.
+ * @bcdDevice_lo: Low end of range of vendor-assigned product version numbers.
+ * This is also used to identify individual product versions, for
+ * a range consisting of a single device.
+ * @bcdDevice_hi: High end of version number range. The range of product
+ * versions is inclusive.
+ * @bDeviceClass: Class of device; numbers are assigned
+ * by the USB forum. Products may choose to implement classes,
+ * or be vendor-specific. Device classes specify behavior of all
+ * the interfaces on a devices.
+ * @bDeviceSubClass: Subclass of device; associated with bDeviceClass.
+ * @bDeviceProtocol: Protocol of device; associated with bDeviceClass.
+ * @bInterfaceClass: Class of interface; numbers are assigned
+ * by the USB forum. Products may choose to implement classes,
+ * or be vendor-specific. Interface classes specify behavior only
+ * of a given interface; other interfaces may support other classes.
+ * @bInterfaceSubClass: Subclass of interface; associated with bInterfaceClass.
+ * @bInterfaceProtocol: Protocol of interface; associated with bInterfaceClass.
+ * @bInterfaceNumber: Number of interface; composite devices may use
+ * fixed interface numbers to differentiate between vendor-specific
+ * interfaces.
+ * @driver_info: Holds information used by the driver. Usually it holds
+ * a pointer to a descriptor understood by the driver, or perhaps
+ * device flags.
+ *
+ * In most cases, drivers will create a table of device IDs by using
+ * USB_DEVICE(), or similar macros designed for that purpose.
+ * They will then export it to userspace using MODULE_DEVICE_TABLE(),
+ * and provide it to the USB core through their usb_driver structure.
+ *
+ * See the usb_match_id() function for information about how matches are
+ * performed. Briefly, you will normally use one of several macros to help
+ * construct these entries. Each entry you provide will either identify
+ * one or more specific products, or will identify a class of products
+ * which have agreed to behave the same. You should put the more specific
+ * matches towards the beginning of your table, so that driver_info can
+ * record quirks of specific products.
