ALSA: hda/realtek: Implement sound init sequence for Samsung Galaxy Book3 Pro 360

Samsung Galaxy Book3 Pro 360 sends a large amount of data to the codec
through hda processing coefficients.  This data was captured using a
modified version of QEMU, but the actual content of the data remains
opaque to me.  Elliding any part of the data seems to cause sound to
not work.
