Change reg in Marvell Armada38X pcie FDT

Browse Source 
Ranges in pcie-controller are unused, so could be changed to match Linux
device tree represntation. Same with interrupt-cells and interrupt-parent.
In PCI controller driver ocd_data are used for matching driver and
choose proper resources acquisition function.
fdt_win_process_child have new argument which provide information
about fdt node containing addresses of MMIO registers.
