When a dm-verity capable is selected, the user will most likely need
the U-Boot script that contains the various dm-verity related
configuration details, needed by U-Boot to build the kernel command
line with the appropriate dm="..." argument.

Therefore, for the Marvell Armada XP GP platform, make sure a FIT
image containing the dm-verity related U-Boot script is produced when
CONFIG_TARGET_ROOTFS_SQUASHFS_HASHED is enabled.
