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

Since the XHCI controller in the PCH is always on the same device
function, the device operations can be statically assigned in the
devicetree and there's no need to bind the XHCI device operations to the
PCI device during runtime via a list of PCI IDs.
