 duplicating its implementation

Subject: [PATCH] usb: gadget: udc: atmel: Use usb_endpoint_num() rather than duplicating its implementation

Reuse existing functionality from usb_endpoint_num() instead of keeping
duplicate source code.

The source code was transformed by using the Coccinelle software.
