In preparation for adding OpenFirmware-to-UEFI translation for "MMIO-like" OFW device path fragments, let's turn the currently exclusive "PCI-like" translation into "just one" of the possible translations. - Rename TranslateOfwNodes() to TranslatePciOfwNodes(), because it is tightly coupled to "PCI-like" translations. - Rename REQUIRED_OFW_NODES to REQUIRED_PCI_OFW_NODES, because this macro is specific to TranslatePciOfwNodes(). - Introduce a new wrapper function under the original TranslateOfwNodes() name. This function is supposed to try translations in some order until a specific translation returns a status different from RETURN_UNSUPPORTED. - Introduce a new Feature PCD that controls whether PCI translation is attempted at all. - The boot option "survival policy" in BootOrderComplete() must take into account if the user was able to select PCI-like boot options. If the user had no such possibility (because the Feature PCD was off for PCI-like translation), then we ought to keep any such unselected boot options.
