ALSA: hda - Add a sanity check of pin / port mapping on i915 HDMI/DP
There is an implicit rule to map between pin NID and port number on
Intel HDMI/DP codec: the mapping is fixed only for NID 0x05, 0x06 and
0x07. For avoiding the possible memory corruption, add a sanity check
for the NID value and splat WARN_ON() for invalid accesses.
