Hello build bot (Jenkins), Furquan Shaikh, Duncan Laurie, Usha P, Pratikkumar V Prajapati, Patrick Rudolph, Aaron Durbin,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/40335

to look at the new patch set (#8).

Change subject: device: Add provision for multiple PCI segments
......................................................................

device: Add provision for multiple PCI segments

Add CONFIG_PCI_SEGMENT_GROUPS with default value 1.

SoC user can override CONFIG_PCI_SEGMENT_GROUPS from respective
SoC Kconfig if SoC has support for multiple PCI segment.

Right now only IA SoC support been added for pci multiple segment
hence IA common code block to address additional programming
based on SoC overide CONFIG_PCI_SEGMENT_GROUPS with > 1 value.

1. SoC to program PCI config space PCIEBAR length
2. Publish MCFG ACPI table for all segments
