The kexec initrd script currently removes the maxcpus=0 kernel arg

not work on all platforms and nr_cpus=1 seems to be a more robust
solution, so with this patch nr_cpus will be removed as well.

The class will perform a basic configuration of a linux kernel
to be used as the balena bootloader. Device types are expected
to inherit it and perform additional device-specific configuration.
