fbe618a45e MdeModulePkg: Fix a PciBusDxe hot plug bug
For a hot plug bridge with device attached, PciBusDxe driver reserves
the resources which equal to the total amount of padding resource
returned from HotPlug->GetResourcePadding() and the actual occupied
resource by the attached device. The behavior is incorrect.
Correct behavior is to reserve the bigger one between the padding
resource and the actual occupied resource.

d40483911c Fix bugs in the PCI bus driver to support SR-IOV.
1. Expand the type of Offset in the _PCI_BAR structure from UINT8 to UINT16, because a VF BAR’s offset may be >= 0x100;
2. Enable ARI Capable Hierarchy for SR-IOV devices at earlier time because FirstVFOffset and VFStride of a SR-IOV device may change after its ARI Capable Hierarchy is set;
3. Change type of PcdSrIovSupport, PcdAriSupport, PcdMrIovSupport from FeatureFlag to [FixAtBuild, PcdDynamics], which allows SR-IOV/MR-IOV/ARI feature can be turn on/off dynamically, typically via a setup option.
4. Change PCI bus scan algorithm in PciScanBus() to prevent the case where some ARI extended functions may be skipped in the scan loop.
