Dhaval 099aff9137 UefiPayloadPkg: Add support for Root bridge parser
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.
