nb/intel/sandybridge: assign host bridge ops in chipset devicetree

Since the host bridge is always function 0 of device 0 on bus 0, 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
