Title:
  [SRU] Update Machine Entries for AMD-Xilinx Kria Boards

Status in flash-kernel package in Ubuntu:
  Fix Released
Status in flash-kernel source package in Jammy:
  Fix Committed

Bug description:
  [Impact]

  Since the model names in the DTBs have been updated in AMD-Xilinx
  kernel, we need to update the machine entries in flash-kernel as well.

  [Where problems could occur]

  The patch adds support for the new model names of AMD-Xilinx Kria
  boards and also separates the boot script.

  So problems can only occur on the following boards:

  * Kria KR260
  * Kria KV260
  * Kria KD240

  [Test Case]

  * Enable proposed updates (https://wiki.ubuntu.com/Testing/EnableProposed)
  * Update flash-kernel to the version in -proposed: sudo apt install -t jammy-proposed flash-kernel
  * Run flash-kernel (if the upgrade didn't already): sudo flash-kernel
  * Reboot: sudo reboot
  * Ensure system boots successfully

  [Regression Potential]

  The only database entry adjusted is for those boards listed, and DEP-8
  tests already cover the functionality of matching boards to database
  entries, including those using wildcards.

  As part of this update, we will also separate the boot script of Kria
  boards from ZCU, so that we won't risk introducing a regression to
  other boards.

  As the patch creates a new boot script for boards (listed above),
  booting should be re-tested against the potentially affected boards
  under the proposed package.
