It looks like this is a CMI 8788 part (and not a generic HDA audio
controller).  The closest fit would be the cmi driver, but it
doesn't appear to support CMI 8788 parts:

cmi.c:#define CMI8338A_PCI_ID   0x010013f6
cmi.c:#define CMI8338B_PCI_ID   0x010113f6
cmi.c:#define CMI8738_PCI_ID    0x011113f6
cmi.c:#define CMI8738B_PCI_ID   0x011213f6

Looking at Linux's sound drivers, our cmi(4) closely matches their cmipci
driver, and their CMI 8788 driver is an entirely separate driver:
