sb/intel/bd82x6x: assign EHCI controller ops in chipset devicetree 

Since the EHCI controllers 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 EHCI device operations to the
PCI devices during runtime via a list of PCI IDs.
