1. sdimage-raspberrypi.wks: increase /boot partition minimal size from 2… …

   …0 to 100
   
   * current aarch64 kernel image alone is 24MB:
     24M tmp-glibc/deploy/images/raspberrypi4-64/Image-raspberrypi4-64-1-6.1.77+git0+43d1723dbe_77fc1fbcb5-r0.1-20110405230000.bin
     and with rpi-bootfiles it takes around 46MB (e.g. this is from kirkstone raspberrypi4-64 build):

     but if you want to update the kernel in place or add some additional files
     later, it might not be big enough, increase the minimal size from 20M to 100M
   
   * reminder (as I forgot about it before):
     "--size" is just minimum
   
     https://docs.yoctoproject.org/ref-manual/kickstart.html
     says:
   
     --size: The minimum partition size. Specify as an integer value optionally followed by one of the units “k” / “K” for kibibyte, “M” for mebibyte and “G” for gibibyte. The default unit if none is given is “M”. You do not need this option if you use --source.
     --fixed-size: The exact partition size. Specify as an integer value optionally followed by one of the units “k” / “K” for kibibyte, “M” for mebibyte and “G” for gibibyte. The default unit if none is given is “M”. Cannot be specify together with --size. An error occurs when assembling the disk image if the partition data is larger than --fixed-size.
