Title:
  Add entries for Pi 4

Status in flash-kernel package in Ubuntu:
  Fix Released

Bug description:
  Impact
  ======

  Apt upgrades performed on a Raspberry Pi 4 complain about missing
  database entries during the flash-kernel trigger. An updated version
  of flash-kernel with a Pi 4 entry in the database is available in the
  following PPA:

      https://launchpad.net/~waveform/+archive/ubuntu/ubpi4

  
  Test Case
  =========

  * Boot the latest eoan daily on a pi3
  * Migrate the boot config to operate on a pi4 (these steps won't be necessary once the gadget snap is updated):

      $ sudo -i
      $ . /usr/share/rpi-config-migration
      $ is_old_config && migrate_config

  * Reboot the card on a pi4
  * Run sudo /usr/sbin/flash-kernel
  * Without the upgrade, it will report "Unsupported platform" with exit code 1
  * Upgrade package to 3.98ubuntu4
  * Re-run sudo /usr/sbin/flash-kernel
  * With the upgrade, should report the usual "Using DTB: bcm2711-rpi-4-b.dtb", etc. with exit code 0

  
  Regression Potential
  ====================

  None; this change only adds the Pi 4 entry to the flash-kernel db. It
  doesn't alter / remove any existing entries or change any code. The
  worst case scenario is that it still doesn't work on the Pi 4.
