Bug description:
  [Impact]

  One of our long-term goals is to support the same set of platforms for both classical Ubuntu and ubuntu-core. We currently provide official images for the Raspberry Pi 3 for both the core16 and core18 bases but do not provide the same for Ubuntu classic.
  Since it's a 'feature' we're essentially lacking since long, we want to have the new device also supported in our current LTS (bionic).

  [Fix]

  For the classic raspi3 support we will be using the ubuntu-image classic image building tool which is specifically designed for creating preinstalled images. The support for that has already been SRUed in the latest ubuntu-image.
  For the full image build support to be complete, the following list of changes need to be backported (SRUed) into the respective stable series:

   * livecd-rootfs - all the changes regarding classic image build, gadget tree selection and raspi3 rootfs generation.
   * u-boot - bionic will need to be updated to at least 2018.03+dfsg1-2ubuntu2.
   * raspi3-firmware (bionic only) - needs to be updated to at least the version we have in cosmic.
