vmm: acpi: Make MBRD _CRS multi-segment aware

Browse Source 
Advertise the PCI MMIO config spaces here so that the MMIO config space
is correctly recognised.

Tested by: --platform num_pci_segments=1 or 16 hotplug NVMe vfio-user device
works correctly with hypervisor-fw & OVMF and direct kernel boot.

Fixes: #3432
