of/unittest: Add empty dma-ranges address translation tests
Intermediate DT PCI nodes dynamically generated by enabling
CONFIG_PCI_DYNAMIC_OF_NODES have empty dma-ranges property. PCI address
specifiers have 3 cells and when dma-ranges is missing or empty,
of_translate_one() is currently dropping the flag portion of PCI addresses
which are subnodes of the aforementioned ones, failing the translation.
Add new tests covering this case.
With this test, we get 1 new failure which is fixed in subsequent
commit:
FAIL of_unittest_pci_empty_dma_ranges():1245 for_each_of_pci_range wrong CPU addr (ffffffffffffffff) on node /testcase-data/address-tests2/pcie@d1070000/pci@0,0/dev@0,0/local-bus@0
