  1. linux-raspberrypi: stop setting powersave as the default CPU governor

    * The defconfigs from the RPi Kernel set `powersave` as the default
      CPU governor, which is a bad idea as that reduces performance by
      setting the CPU frequency to the minimum one.
    
    * In case of a Yocto build user-space is not configured by default
      to change the CPU governor, so `powersave` will remain the CPU
      governor and it will slow down everything.
    
    * I submitted a fix for those defconfigs to upstream here:
      raspberrypi/linux#5666
      However, we shouldn't wait until that is accepted and backported
      to all the stable branches (if ever is).
    
    * This patch unsets the selection of `powersave` as the default CPU
      governor.
    
    * Then the CPU governor that will be selected as default after this
      patch will be the Linux's default one that is either `ondemand` or
      `schedutil` depending on the Kernel version.
