sb/intel/bd82x6x: assign PCH HDA controller ops in chipset devicetree 

Since the HD audio controller in the PCH are always on the same device
functions, the device operations can be statically assigned in the
devicetree and there's no need to bind the host bridge device operations
to the PCI device during runtime via a list of PCI IDs.

TEST=Lenovo X220 still boots to Linux and audio still works
