bootloader: Add device-tree-support? option.
In some specific cases where the device tree file is already loaded in RAM, it can be preferable that the bootloader does not try to use a device tree from the Linux kernel tree. * gnu/bootloader.scm (<bootloader-configuration>)[device-tree-support?]: New field. * gnu/bootloader/extlinux.scm (extlinux-configuration-file): Add FDTDIR line based on <device-tree-support?> field of <bootloader-configuration>. * doc/guix.texi (Bootloader Configuration)[device-tree-support?]: Add documentation for the new field.
