test: pci: Test PCI address conversion functions

Add tests for the functions dm_pci_bus_to_phys() and
dm_pci_phys_to_bus() which convert between PCI bus addresses and
physical addresses based on the ranges declared for the PCI controller.

The ranges of bus#1 are used for the tests, adding a translation to one
of the ranges to cover more cases.
