sb/intel/ibexpeak: Implement PCH function disable in chip_ops

This does the following:
- implement a PCH disable function that will be called by the PCI
  drivers as part of their chip_ops
- removes the iobp_x calls as those don't exist on ibexpeak
- complete the devicetree with to be disabled PCI devices for the
  chip_ops to be called
- Clean up some code copied from bd82x6x
