ANDROID: usb: Optimize the problem of slow transfer rate in USB accessory modecommon-android14-5.15
The data transfer rate using Google Restore in USB3.2 mode is slower,
only about 140MB/s at 5Gbps.
The bMaxBurst is not set, and num_fifos in
dwc3_gadget_resize_tx_fifosis 1, which results
in only 131btye of dwc3 ram space being allocated to ep.
Modify bMaxBurst to 6.
The 5Gbps rate increases from 140MB/s to 350MB/s.
The 10Gbps rate is increased from 220MB/s to 500MB/s.
