Because of NixOS's generate-config.pl tries to answer 'M' to as much configs as possible, this exposes the wrong Kconfig in the RPi-specific code which is added in the new kernel tree intended to support RPi 5. Add kernel patches to fix the Kconfig, which results in the relavant part being disabled on the RPi 3 build of the kernel.
