[U-Boot] [PATCH] fsl_pci_init: Make fsl_pci_init_port() PCI/PCIe aware

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
