MLK-22577-2: usb: cdns3: Change the max packetsize of interrupt endpoint

When use ep1out interrupt endpoint to receive data in sdp, the max
packetsize of ep1out is set to 1024. But in cdns3 gadget driver, the
max packetsize is limited to 512 bytes in high speed. So we can't
implement data download through ep1out of cdns3 driver, here need
change the max packesize of interrupt endpoints to 1024.
