arm64: wipe old initrd addresses when patching the DTB
When copying the DTB from the current kernel, if the user didn't pass an
initrd on the command-line, make sure that the new DTB doesn't contain
initrd properties with stale addresses. Otherwise the next kernel will
try to unpack the initramfs from a location that contains junk, since
the initial initrd is long gone:
[ 49.370026] Initramfs unpacking failed: junk in compressed archive
This issue used to be hidden by a successful recovery, but since commit
ff1522bb7d98 ("initramfs: cleanup incomplete rootfs") in Linux, the
kernel removes the default /root mountpoint after failing to load an
initramfs, and cannot mount the rootfs passed on the command-line
anymore.
