The support for dualboot was integrated on meta-digi-dualboot layer, but it
really depends only on environment variable 'dualboot' so we'd better
integrate the support on the scripts in meta-digi, to avoid synchonization
problems between both layers.
This also allows to be able to easily enable dualboot in U-Boot with the
variable, without needing to update the script on the linux partition.

On these boot scripts, this variable is not used, so we can remove it.
Besides, it's generated by U-Boot code.

This overlay added cooling devices for all quad cores.
On the latest BSP, the SoC device tree include contains all four
cooling devices and the newest U-Boot is able to delete the nodes
for non-existing cores, so there's no need for this overlay
anymore.
