CONFIG_ARCH_MULTI_V7 might be required too

RK3566 is ARMv8-A (it has only 4 Cortex A-55, which are ARMv8.2-A) and CONFIG_ARCH_MULTI_V7 is for ARMv7 (if I understand correctly). So at first sight, it should not be required but if my real test fails, I'll try to add it.

Thanks, this is weird because it says it's for Rockchip Cortex-A9 so I'll try without it and if it doesn't work, I'll try to add it.
If I add it, I'll try to use the SDK container to build locally and make the change if it helps.

@sambonbonne the image was built, you can download it and try it from the github actions artifacts page. https://github.com/flatcar/scripts/actions/runs/12575139169?pr=2556 |

The vmlinuz image increase is pretty big, by 3MB, which is more than the space allowed for the updates to work, that s why some of the tests failed. But as a PoC, you can try first the resulting image and see if it works. |

@ader1990 thank you! I had some problems when trying to edit the partition layout of my SD card with I understand 3MB is too big, unfortunately I don't know enough about "kernel things" to help on this so if I manage to have a working image, I hope we will be able to reduce the added size or find an alternative. |

Set CONFIG_ARCH_ROCKCHIP
After some discussion on Matrix about Odroid M1S (based on RK3566), I made this PR to enable Rockchip arch in the kernel.
The goal is to test the generated aarch64 image on my hardware and to see if the initrd size is not increased to much before discussing about the possible inclusion of this configuration in Flatcar.
How to use
Installing the image in Odroid M1S requires U-Boot binaries and multiple steps. I will add testing commands if it works on my hardware and someone want to try it on real hardware.
Testing done
No testing for now. I plan to download the generated image (when it's generated) and install it on my hardware to test if it boots.
