lib, fdt: move fdtdec_get_int() out of lib/fdtdec.c
move fdtdec_get_int() out of lib/fdtdec.c into lib/fdtdec_common.c as this function is also used, if CONFIG_OF_CONTROL is not used. Poped up on the ids8313 board using signed FIT images, and activating CONFIG_SYS_GENERIC_BOARD. Without this patch it shows on boot: No valid FDT found - please append one to U-Boot binary, use u-boot-dtb.bin or define CONFIG_OF_EMBED. For sandbox, use -d <file.dtb> With this patch, it boots again with CONFIG_SYS_GENERIC_BOARD enabled.
