[PATCH v2 0/1] Fix booting kernels with ATAGS and extlinux

Currently, if boot with extlinux.conf and do not set the fdt U-Boot will provide its own device tree. This behavior is beneficial if the U-Boot device tree is in sync with Linux, but it totally halts the booting of pre-dtb kernels (3.4 for example) since it uses ATAGs. To fix this, pass `-` in the fdt extlinux field as a signal that no tree should be used.

Tested with 3.4 legacy kernel and mainline 6.7 kernel on P895 (lg_x3 board).

--- Changes form v1 - Added CONFIG guards - Clarified documentation ---
