[ALSA] hda-codec - Initial support of the Mitac 8252D (based on ALC883)

The attached patch adds initial support of the Mitac 8252D
(http://www.mitac-mtc.com.tw/English/products/8252Dspec.htm).
Working:
 - Front speakers (volume + mute)
 - Center/LFE speakers (volume + mute)
 - HP out (with Front Volume)
 - HP individual mute switch
 - HP Jack sense
 - Front Mic and its volume
Not tested:
 - external mic and its volume
Not working while now:
 - Mic Jack sense
Questionable:
 - is Mic have Jack sense?
 - one or two Mic volume controls?
 - CD/Line-in: presense in the mixer
