In gadget mode, USB connections are sluggish. The device won't send
packets to the host unless the host sends packets to the device. For
instance, SSH-ing through the USB network would apparently not work
unless you're flood-pinging the device's IP.
Add the property snps,usb2-gadget-lpm-disable to the dwc3 node, which
seems to solve this issue.
