Title:
  [SRU] flash-kernel to support xilinx kria platforms with noble kernel

Status in flash-kernel package in Ubuntu:
  Fix Released
Status in flash-kernel source package in Noble:
  New
Status in flash-kernel source package in Oracular:
  New

Bug description:
  [ Impact ]

   * With the current version of flash-kernel, users wont be able to
  boot into xilinx devices using optimised noble kernel because of the
  renaming of device-trees in kernel and cma configuration changes.

   * We need to fix this issue to keep support for xilinx devices in
  noble as well. This must not be back-ported into jammy since the
  kernel in jammy keeps the old names for device-trees and cma
  configuration in there didn't change

   * Patch will fix the issue by updating bootscript and `its` file to
  point correct device-tree files.

  [ Test Plan ]

   * Flash the new image generated with new flash-kernel that has this fix
   * Try booting with new image
   * You should be able to reach the login prompt and be able to login using default username and password
   * This must work for all Kria devices listed below:
    - KV260
    - KR260
    - KD240

  [ Where problems could occur ]
   * This change could only impact Xilinx Kria devices since it will only touch the files used by Xilinx Kria platforms including the ones listed above in test plan
   * Since this is an enablement patch for Ubuntu Noble image on Xilinx Kria platforms, there shouldnt be an impact to devices in the field.
   * If the patch is broken then the devices listed above will still continue to not work.

  [ Other Info ]
   
   * This is based on changes in new optimised kernel: https://code.launchpad.net/~canonical-kernel/ubuntu/+source/linux-xilinx/+git/noble
