Bug description:
On the Pi 4 board revision 1.4 (of which the 8Gb model is currently
the main example), the VL805 USB controller doesn't appear to be
recognized by the 5.3 kernel. To reproduce:
* Flash a current bionic image (e.g.
http://cdimage.ubuntu.com/releases/bionic/release/ubuntu-18.04.4-preinstalled-server-arm64+raspi4.img.xz)
* Boot the card on an older Pi model (3, 4 rev 1.2, etc.)
* sudo add-apt-repository ppa:waveform/firmware
* sudo apt install linux-firmware-raspi2 (the rev 1.4 requires a newer
firmware package to boot; this PPA contains a test package with a back-ported
firmware)
* Boot the card on a Pi 4 rev 1.4
* Observe USB2 and USB3 ports do not work
* Boot the card on an older Pi 4 rev 1.2
* Observe USB2 and USB3 ports do work
