ALSA: hda - Add missing hda_gen_spec to struct via_spec

Browse Source 
The commit [4b527b65 ALSA: hda - limit internal mic boost for Asus
X202E] introduced the use of auto-parser code, but it forgot to add
struct hda_gen_spec at the head of codec->spec which the auto-parser
assumes silently.  Without this record, it may result in memory
corruption.

This patch adds the missing piece.
