We only use 5.15 kernel. So remove all those unnecessary symbols
referencing 5.10 or 5.15 kernel.
Can be found with:
git grep -E 'LINUX_5_1(0|5)'
Note that we remove the dependency from "sound-soc-chipdip-dac" instead
of removing the complete kernel package. The 5.15 version bump forgot to
delete the "@LINUX_5_10" dependency. The kernel package is still needed
in 5.15 kernel.
