I pushed linux-libre 5.6 to master *without* setting it as the default
linux-libre version; only added linux-libre-arm64-generic-5.6 and
linux-libre-arm-generic-5.6 based on it.

Attached are the remaining patches to switch it to the default.

I still haven't thoroughly audited the config changes; this simply
copies 5.4-*.conf to 5.6-*.conf in the first patch, and in the second
patch updates them to 5.6 produced by building the package.

By splitting it into two patches, this allows diffing from the old 5.4
configs, but should maybe be squashed if this gets pushed to master.


Thanks for your review!
