Per PCI Spec, the option ROM BAR is 32bit so the maximum option ROM
size can be hold by UINT32 type.

Per PI spec, the PciEnumerationComplete protocol installation
should be after PciIo installation.
Today's implementation installs the PciEnumerationComplete
after hardware enumeration is completed, but before PciIo
installation.
The change corrects the spec/implementation gap.
The change also benefits certain implementation that depends on
the PciIo handle in PciEnumerationComplete callback.

If the current PCI configuration requires no resources to be allocated at
all (i.e., unpopulated bus), the PCI enumeration code creates a single
ACPI_ADDRESS_SPACE_DESCRIPTOR memory descriptor with all fields cleared.
This is rejected by the SubmitResources() implementation of the generic
PciHostBridgeDxe in the following way:
PciHostBridge: SubmitResources for PcieRoot(0x0)
Mem: Granularity/SpecificFlag = 0 / 00
Length/Alignment = 0x0 / 0x0
PciBus: HostBridge->SubmitResources() - Invalid Parameter
ASSERT_EFI_ERROR (Status = Invalid Parameter)
ASSERT [PciBusDxe] .../PciBusDxe/PciLib.c(561): !EFI_ERROR (Status)
So instead, create the empty configuration as a single entry of type
EFI_ACPI_END_TAG_DESCRIPTOR.

When looping through all PCI functions, code should not look for functions
1-7 if function 0 is not present or if function 0 indicates the device is
not multifunction. Prior to this fix the code would use stale data in a
buffer to determine if a device is multifunction even if function 0 is not
present. This fixes a code bug and provides very small performance
improvements.
PCI 2.3 Specification states: They [multifunction devices] are also
required to always implement function 0 in the device. Implementing other
functions is optional and may be assigned in any order.
