usb: musb: cppi41: fix not transmitting zero length packet issue
CPPI TX does not transmit ZLP for TX transfers which
- transfer size is multiple of EP packet size,
- and URB_ZERO_PACKET is set in urb->transfer_flags.
The fix is transmitting the ZLP using PIO mode after the CPPI TX is
done.
Validated using the following usbtest write case in MUSB host mode.
# testusb -t1 -c1
