BugLink: https://bugs.launchpad.net/bugs/2065829 The raspi kernel doesn't have BTF enabled which means advanced BPF features can't be used. With Pi 4 and 5, more and more users want to use those, so let's enable BTF. I.e., remove the raspi overrides and use the master kernel's config options. The resulting uncompressed kernel image is ~4MB bigger and the available memory shrinks by ~9MB which should be OK for Pi 4 and 5.
