purism/librem13v2: Add audio support
Initialize the audio codec without depending on DSP binary blobs. The hda_verb.c was copied from the intel/kblrvp rvp7 variant, and the hda_verb.h file was copied from the purism/librem13. The IoBufferOwnership FSP option in devicetree has to be 0 for the azalia driver to work.
