Hi ， I'm using the 4*A53 with DWC3 USB controller, my hardware to work
like a USB camera and so make use of the USB 3.0 UVC gadget driver。
usb3.0 isoc transfer with missisoc -18，larger maxburst is set, the
more -18 appears。
but from trace info, the trb has been put in advance。
test setting:
dwc3 driver version：5.12
PC： potplayer
maxpacket : 3072
maxburst : 15
interval : 1
UVC_NUM_REQUESTS: 8
dmesg info：
