media: coda: jpeg: explicitly disable thumbnails in SEQ_INIT

Browse source 
Explicitly clear DEC_SEQ_JPG_THUMB_EN during sequence initialization.
Not clearing the register does not cause problems, since the only other
codec (MPEG-4 decode) that writes to this register happens to always
write 0 as well.
