Support LicheeRV and PolarFire RISC-V platforms in jammy

[Łukasz Zemczak]

[Impact]

As part of our HWE story, we want to support two new platforms (available in kinetic/lunar): the LicheeRV and the PolarFire Icicle Kit. To do this, we need to backport some of the livecd-rootfs changes for building those images.

https://code.launchpad.net/~xypron/livecd-rootfs/+git/livecd-rootfs/+merge/433185 list all the changes needed:

* Add support for the LicheeRV board (SUBARCH=licheerv)
* Add support for the PolarFire Icicle Kit board (SUBARCH=icicle)
* Reduce initrd size for Nezha and LicheeRV boards
* Use efi=debug earlycon on kernel command line

[Test Case]

Build official PROPOSED=1 images for jammy for licheerv and icicle SUBARCHes.

Additionally to this, make sure existing RISC-V preinstalled images still build correctly. Reach out to the CPC to check if cloud images for RISC-V still build correctly with the new livecd-rootfs.

[Regression Potential]

The only regression potential is breaking other RISC-V related images, but this should be mitigated by the additional testing steps provided in the Test Case.

If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!
