bootscript: Remove device specific device trees

We want to overlay the device tree in the install script. Thus we can
create a device specific device tree with the generic name
"devicetree.dtb".

This removes the neccessary pacthing of the boot.cfg.

However, currently we cannot load the devicetree with the bootloader and
thus append the device tree to the kernel at installation time and name
the resulting binary "linuximage".
