ASoC: SDCA: Add code to parse Function information

Browse source

Add a helper function to parse all the Function and Entity
information from ACPI. In SDCA each device may have several Functions
and each corresponds to a specific audio capability such as say
amplifier playback or microphone capture. Each Function then contains
a number of Entities that represent individual parts of the audio
signal chain and are linked together in a graph similar to DAPM.
