initrd should be optional on pi

[Dave Jones]

At present, flash-kernel assumes an initrd is always present when copying files to the boot partition on the Raspberry Pi. Furthermore, the uboot script (bootscr.rpi) also assumes an initrd is present. This should be changed to permit the kernel team to remove the initrd in future.

This bug was fixed in the package flash-kernel - 3.98ubuntu12

---------------
flash-kernel (3.98ubuntu12) focal; urgency=medium

  * Support "raspi" kernel flavor in addition to "raspi2" (LP: #1868071)
  * Permit initrd to be missing in flash-kernel and the pi u-boot script
    (LP: #1867791)
  * Backport optional initrd changes from upstream to reduce our delta
  * Move the container test from initramfs and kernel hooks to main to prevent
    flash-kernel ever running in a container (LP: #1863145)
  * Remove FLASH_KERNEL_SKIP; it's no longer used in livecd-rootfs
