Previously fsl_pci_init_port() always assumed that a port was a PCIe port and would incorrectly print messages for a PCI port such as the following on bootup: PCI1: 32 bit, 33 MHz, sync, host, arbiter Scanning PCI bus 00 PCIE1 on bus 00 - 00
This change corrects the output of fsl_pci_init_port(): PCI1: 32 bit, 33 MHz, sync, host, arbiter Scanning PCI bus 00 PCI1 on bus 00 - 00
