With the new syntax bitclock-master and frame-master properties can explicitly indicate the dai-link bit-clock and frame masters with a phandle. This patch also makes the minimal changes to simple-card for it to work with the updated snd_soc_of_parse_daifmt(). Simple-card appears to be the only user of snd_soc_of_parse_daifmt() for now.
