[ 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
