usb: gadget: udc-xilinx: Use USB API functions rather than constants

Browse Source 
Use the function usb_endpoint_num() and usb_endpoint_type()
rather than constants.

The Coccinelle semantic patch is as follows:

@@ struct usb_endpoint_descriptor *epd; @@

- (epd->bEndpointAddress & \(USB_ENDPOINT_NUMBER_MASK\|0x0f\))
+ usb_endpoint_num(epd)

@@ struct usb_endpoint_descriptor *epd; @@

- (epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\))
+ usb_endpoint_type(epd)
