After much review discussion I am sponsoring 2019.07+dfsg-1ubuntu4 to
Focal and 2019.07+dfsg-1ubuntu3~18.04.1 to Bionic (I tweaked the
version).

On the Bionic backport, I note that it's essentially impossible to
review all the upstream changes for functional behaviour changes to
users on Bionic, so we will have to rely entirely on QA instead. The
alternative is to not enable Pi 4 on Bionic at all, so on balance this
seems like the only reasonable path forward.

Eoan needs looking at. Some changes from 2019.07+dfsg-1ubuntu3 to
2019.07+dfsg-1ubuntu4 may need backporting in an SRU to Eoan to make
sure the upgrade path Bionic->Eoan->Focal works correctly at both of
those points. I suggest this needs resolving before the Bionic SRU lands
in the updates pocket, but leave that decision to the SRU reviewer.

We also identified a race condition: if flash-kernel is deconfigured to
resolve the Breaks and then upgraded afterwards, flash-kernel won't run
itself. This will be fixed separately in flash-kernel and will need no
further changes to u-boot.
