kernel-fitimage: dtb sections named by their filenames and one config section for each dtb
Before this, dtb sections were named by their position index in KERNEL_DEVICETREE. Also there was only one item in the config section, so only the first dtb was seen by the bootloader. This patch adds a config section for each dtb named by the dtb filename. This is what bootloaders usually know about the machine they run on.
