Subject: [PATCH v2 2/3] of: address: Remove duplicated functions

The recently added of_bus_default_flags_translate() performs the exact
same operation as of_bus_pci_translate() and of_bus_isa_translate().

Avoid duplicated code replacing both of_bus_pci_translate() and
of_bus_isa_translate() with of_bus_default_flags_translate().
