In D21096 BUS_TRANSLATE_RESOURCE was introduced to allow LinuxKPI to get physical addresses in pci_resource_start for PowerPC and implemented in ofw_pci. When the translation was implemented in pci_host_generic in 372c142b, this method was not implemented; instead a local static function was added for a similar purpose. Rename the static function to "_common" and implement the bus function as a wrapper around that. With this a LinuxKPI driver using physical addresses correctly finds the configuration registers of the GPU. This unbreaks amdgpu on NXP Layerscape LX2160A SoC (SolidRun HoneyComb LX2K workstation) which has a Translation Offset in ACPI for below-4G PCI addresses.
