apalis-tk1: add optional pcie evalboard initialisation

Implement optional PCIe EvalBoard initialisation which properly reset the PLX
(now Avago) PEX 8605 PCIe switch plus PCIe devices on the Apalis Evaluation
carrier board.

Please note that you will have to enable the second PCIe port in the dts as well
e.g.:

                pci@2,0 {
                        status = "okay";

While at it also get rid of the DECLARE_GLOBAL_DATA_PTR which is probably a
remnant of the Apalis T30 board file where we use it to get the memory size.
