ff4025c5f7 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.

7f5efd90e5 intel/bd82x6x: Use generated ACPI PIRQ
Enable change Ic6b8ce4a9db50211a9c26221ca10105c5a0829a0
(sb/intel/common: Automatically generate ACPI PIRQ) for BD82X6X.

This generates the main ACPI _PRT table automatically based on the
chipset registers.

Tested on Intel NUC DCP847SKE with Linux 4.13.14:

928c6c6336 mainboard/asrock: add ASRock B75 Pro3-M
Tested:

- i5-3550 and DIMM configurations: 2+0+2+2, 0+2+2+2, 2+2+2+2, 4+2+4+2
- debug output from serial port, EHCI debug port not found
- Arch Linux (Linux 4.11.5) loaded from SeaBIOS, GRUB2, and Linux payload
- all PCI and PCI Express slots

Issues:

- sometimes the machine fails to boot, with serial debug output it can
  be seen it stucks after SMM initialization, and more likely to fail
  to boot when serial cable is attached
- no S3 resume (not tested in vendor firmware)
