ASoC: core: Allow codec_conf DT lookups to match parent of_node

Browse Source 
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
codec_conf mappings we should match against both the devices of_node and
the devices parent's of_node, as is already done for DAIs and platform
components.
