First, add set_dailink_daifmt() function, so dai_fmt can be updated by the configuration in dai-link sub node. Second, remove codec phandle from required property in dai-link sub node. For example, user possibly needs to update dai-format for all etdm co-clock dai-links, but codec doesn't need to be specified in capture dai-link for a speaker amp.
