In order to properly enable multisegment RB, we need to grab ecam data from the FDT for each bridge. Current UNIVERSAL_PAYLOAD_PCI_ROOT_BRIDGES struct from MdeModulePkg does not include definition for ecam. In order to maintain backward compatibility and also avoid diverging too much from core, we are going to define a new HOB for UPL segment information and pass it to GetPciSegmentInfo function. Ths function then grabs specifically ecam info from the segment hob along with other rb specific information to create final RB info required by multi segment PCI driver. Additionally we would like to support legacy implementations which rely on ACPIBoard HOB to fill up segment info. So if UplSegmentInfo Hob is not found we try and look for other hob.
