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.
