Add entries for Pi 4

Bug Description


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:

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.

Looks fine, I have sponsored this for eoan. This doesn't explicitly require an FFe because it's basically a bugfix for the new pi4 support that we already had an FFe for.
