For devices implemented as a MFD it is common to only have a single node in devicetree representing the whole device. As such when looking up components in soc_find_components we should match against both the devices of_node and the devices parent's of_node, as is already done in the rest of the ASoC core. This causes regressions for some DAI links at the moment as soc_find_component was recently added as a check in soc_init_dai_link.
