ppc/8xxx: Remove is_fsl_pci_agent

All users of is_fsl_pci_agent have been converted to fsl_is_pci_agent
that uses the standard PCI programming model to determine host vs
agent/end-point.

- * in agent/end-point mode for the given interface.

- * The same idea is true of the cfg field.  The bit will be set if the

  * On MPC86xx/PQ3 based systems:
- *   we extract cfg_host_agt from GUTS register PORBMSR
  *   we extract cfg_IO_ports from GUTS register PORDEVSR
  *
  * cfg_IO_ports only exist on systems w/PCIe (we set cfg 0 for systems
