usb: dwc3: gadget: increase intr ep resize tx fifo to 64B

Browse Source 
For RV1109/RV1126 platforms, it resizes the tx fifos for
all of the usb device endpoints by default, it aims to
support UVC composite device, so just only set 16 bytes
for the tx fifo of the intr endpoints. But for the other
USB functions, like MTP function, it requires 64 bytes
tx fifo for its intr endpoint.
