sam460ex: Use type cast macro instead of simple cast

Browse source 
Use the PCI_BUS type cast macro to convert result of qdev_get_child_bus().
Also remove the check for NULL afterwards which should not be needed
because sysbus_create_simple() uses error_abort and we create the PCI
host object here that's expected to have a PCI bus so this shouldn't
fail. Even if it would fail that would be due to a programmer error so
an error message is not necessary.
