[SRU] Creating FIT images is not supported

[Alfonso Sanchez-Beato]

[Impact]

flash-kernel does currently not support creating FIT images. There are some platforms where this is preferred, for instance for the Kria SOM platform.

This have been just fixed in flash-kernel 3.104ubuntu4 in impish (dev) (LP: #1931278), and we would like this ported back to hirsute/focal to support Kria SOM platform in focal.

[Test Plan]

For testing, a Kria SOM device is needed. By install flash-kernel with the fix, a file in path /boot/firmware/image.fit will be created, and the system should be able to boot.

[Where problems could occur]

The change adds new functionality which should not interfere with the previous one. However, there is some small potential for a regression happening. If that is the case, some hardware platforms that use flash-kernel might not be able to update the bootloader or will break it, making the system unable to boot.

I have verified in focal. Installation generated FIT images on my Kria system, and reboot was successful. I cannot verify on hirsute though as I do not have a Kria image for that Ubuntu version.

I think the ageing we got on hirsute is enough of a verification on hirsute.
