The current way how command parameters, particularly "fdt addr," are
handled makes it a bit complicated to add a subcommand-specific parameter.
So just refactor the code and extract efi_handle_fdt().
This commit is a preparatory change for enhancing bootmgr sub-command.

Revert "fixup! fixup! cmd: bootefi: carve out fdt parameter handling"
This reverts commit abc315426e37bdfb96a48d23c1fc96399b68baa5.
