Subject: [PATCH 0/1] usb: dwc2: fix hot plugging on Amlogic devices

This is a follow-up to an issue I had a while ago but never had the
time to debug it: [0]
Short summary:
- on Meson8b USB devices are only detected if they are plugged in
  before booting Linux
- if they are plugged in after booting Linux they are not detected
  (except when running "lsusb -v" as a workaround)

Christian Hewitt made me aware of a similar issue that was fixed for
Rockchip devices. This single patch applies the same fix to the
Amlogic devices as well.
