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.
