ppc4xx: remove invalid access to PCI_BRDGOPT2 register

This patch removes an invalid call to pci_write_config_dword to
PCI_BRDGOPT2 register. This function must not be used from pci_target_init
and is also at the wrong place. The correct call is done later in
pci_target_init via pci_hose_write_config_dword.
