ArmVirtualizationPkg/PciHostBridgeDxe: handle 0 in GetProposedResources()
When there are no devices connected to the root bridge, no resources are
needed. GetProposedResources() currently considers this an invalid
condition (the PI spec doesn't regulate it).
Emitting an empty set of EFI_ACPI_ADDRESS_SPACE_DESCRIPTORs, followed by
the required EFI_ACPI_END_TAG_DESCRIPTOR, allows
PciHostBridgeResourceAllocator() [MdeModulePkg/Bus/Pci/PciBusDxe/PciLib.c]
to advance.
