The new is_serdes_configured covers a broader range of devices than the PCI specific code. Use it instead as we convert away from the is_fsl_pci_cfg() code.
Additionally move to setting LAWs for PCI based on if its configured. Also updated PCI FDT fixup code to remove PCI controllers from dtb if they are not configured.
