When U-Boot proper is compiled with CONFIG_MULTI_DTB_FIT and tries to call uncompress_blob(), it fails with -ENOTSUPP. This is because the full implementation of this function which includes compression is available only in SPL. In U-Boot proper or if the compression is not enabled, the blob is not compressed and thus can be passed to locate_dtb_in_fit() in fdtdec_setup() without any changes. Pass the blob without any changes if compression is not enabled instead of failing.
