Modify the recovery and trustfence initramfs scripts to be able to encrypt any
partition on the internal storage media, not just the rootfs.
To implement this functionality, add a new recovery command called
'encrypt_partitions'. When used, this command must contain a comma-separated
list of the partitions that are to be encrypted by the end of the recovery
process, including partitions that were already encrypted beforehand. Any
partition that isn't in the list will be unencrypted. If the command is absent,
no changes will be made, but it's possible to pass an empty command to
unencrypt all partitions.
Include a blacklist to avoid encrypting partitions that shouldn't be encrypted,
such as partitions that need to be accessed by the ROM code/U-Boot or
partitions that contain encryption keys.
While at it, remove unnecessary "get_kernel_version" function from the script.

The poweroff command is not available in the initramfs due to a missing
sysvinit/systemd dependency. Use the busybox "halt" command, since it's
available regardless of the init manager used. Rework the error message and
script variables accordingly.
