tools/testing/cxl: Add bridge mocking support

In preparation for cxl_acpi walking pci_root->bus->bridge, add that
association to the mock pci_root instances.

Note that the missing 3rd entry in mock_pci_root[] was not noticed until
now given that the test version of to_cxl_host_bridge()
(tools/testing/cxl/mock_acpi.c), obviated the need for that entry.
However, "cxl/acpi: Improve debug messages in cxl_acpi_probe()" [1]
needs pci_root->bus->bridge to be populated.
