Maurice Ma 0613ccbd13 CorebootPayloadPkg/PciHostBridgeLib: Fix the wrong PCI resource limit
The current PCI resource limit calculation in CorebootPayloadPkg
PciHostBridgeLib is wrong. Adjusted it to match the PciHostBridge
driver's expectation.

Maurice Ma 8a3a97814e CorebootModulePkg/PciHostBridgeLib: Fix PCI 64bit memory BAR size issue
The current PCI 64bit memory BAR size calculation in PciHostBridgeLib
assumes all 32 bits in the upper BAR are fully writable. However,
platform might only support partial address programming, such as 40bit
PCI BAR address. In this case the complement cannot be used for size
calculation.  Instead, the lowest non-zero bit should be used for BAR
size calculation.

Maurice Ma 69787a9d31 CorebootPayloadPkg: Use generic PciBus/PciHostBridge driver
Current CorebootPayloadPkg uses PciBusNoEnumerationDxe and
PciRootBridgenoEnumerationDxe copied from the DuetPkg. Now it will
switch to use the standard PciBusDxe and PciHostBridgeDxe from
MdeModulePkg. As a result, a coreboot specific PciHostBridgeLib
is added to collect pre-allocated PCI resources.
