When this BOOLEAN member is FALSE, and the caller tries to set up a DMA
transfer between a PCI device and a host buffer not entirely under 4GB,
then "MdeModulePkg/Bus/Pci/PciHostBridgeDxe" sets up a bounce buffer under
4GB, in the implementation of EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.Map().
Since that's exactly what RootBridgeIoMap() does in
"OvmfPkg/PciHostBridgeDxe/PciRootBridgeIo.c", stick with it in this
conversion.

In this patch we import the scan for extra root buses from the
InitializePciHostBridge() function, in file
"OvmfPkg/PciHostBridgeDxe/PciHostBridge.c".
For the time being, the InitRootBridge() and UninitRootBridge() functions
are just placeholders.
The PciHostBridgeGetRootBridges() API expects us to return the
PCI_ROOT_BRIDGE structures in a contiguous array, instead of a linked
list. Therefore the following bits have to be converted manually:
(1) The array is allocated in advance, in a single step.
(2) The calculation of the array size depends on an explicit
multiplication, which we must check against overflow. Since more than
255 extra root bridges make no sense anyway, we use (1 + 255) as the
limit on the main plus all extra root bridges. This also ensures that
the UINTN multiplication doesn't overflow.
(3) The PciHostBridgeDxe code decrements "ExtraRootBridgesLeft" to
terminate the scanning early. Here we need track the increasing count
of used array elements as well, so we employ "ExtraRootBridges" as a
constant limit, and increment the new local variable "Initialized".
(4) The prototypes of InitRootBridge() and UninitRootBridge() reflect that
the PCI_ROOT_BRIDGE structure is allocated by the caller; only
in-place initialization is necessary.
Additionally, macros are employed for standard PCI quantities, from
"MdePkg/Include/IndustryStandard/Pci22.h":
- MAX_PCI_DEVICE_NUMBER (31) is replaced with PCI_MAX_DEVICE (same),
- the constant 255 is replaced with PCI_MAX_BUS,
- the (RootBridgeNumber < 256) condition is replaced with
(RootBridgeNumber <= PCI_MAX_BUS).
