sb/intel/bd82x6x: Reduce function-disable mess
Most affected boards set the function disabled (FD) register to an arbitrary state dumped from systems running the vendor BIOS. This makes it impossible to enable the devices in devicetree and a pretty big mess of course because nobody cared to keep the register in sync with the devicetree. To get completely rid of most of the writes to FD, move setting of PCH_DISABLE_ALWAYS into the southbridge code where it belongs.
