sb/intel/bd82x6x: Follow PCH BIOS spec
PCH BIOS spec says that BIOS must clear BIT26 in register 0x338
in PEI, as done on lynxpoint.
Copy and adapt the lynxpoint code to do the same on bd82x6x.
Add special case for UM77 chipset, which only has 4 PCIe ports.
Test: System still boots and all PCIe ports are fully working.
