Current asoc_simple_card_parse_daifmt is keeping backward compatibility for bitmaster/framemaster which didn't use phandle. The keep compatibility, it is checking prefix length, but it is too strict. let's loosen it. Otherwise, OF-graph base sound card which doesn't have prefix can't detect daifmt.
