Piyush Mehta 8cb339f1c1 usb: gadget: udc-xilinx: replace memcpy with memcpy_toio ... For ARM processor, unaligned access to device memory is not allowed. Method memcpy does not take care of alignment. USB detection failure with the unaligned address of memory access, with below kernel crash. To fix the unaligned address the kernel panic issue, replace memcpy with memcpy_toio method.
