dtb symbols (__dtb_start, __dtb_end) are already defined using
RO_DATA_SECTION. This duplicated dtb section is a leftover used by
Kalray internal tools to patch the dtb when loading the elf on a
target. Remove it to keep only one symbol definition.

<config.h> is per-board config file, which is only allowed for old
boards.

For new boards, the top Makefile creates an empty include/config.h

kvx does not have config.h, so #include <config.h> is useless.

Also, remove meaningless board-$(CONFIG_GENERIC).
