ALSA: HDA: Make hda sound card usable for Loongson

Lemote A1004(Laptop) and A1205(All-In-One) use Conexant's hda codec,
this patch modify patch_conexant.c to add Lemote specific code.

Both A1004 and A1205 use the same pin configurations, but A1004 need
to increase the default boost of internal mic.
