[RFC,v5,5/8] drm/i2c: tda998x: Remove include/sound/tda998x.h and fix graph parsing

Move struct tda998x_audio definition to tda998x_drv.c and remove
include/sound/tda998x.h. There is no external use for struct
tda998x_audio.

Fix graph parsing to allow ports to be inside a separate "ports"-node as
specified in Documentation/devicetree/bindings/graph.txt.
