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.

Known issues:
- Native raminit fails timC calibration with the RAM I have.
- Technical Product Specification mentions overcurrent protection
for back panel and front panel USB connectors, but I haven't
been able to trigger it with either native fw or coreboot
(tried up to 2.5A load).
