ARM: orion5x: convert RD-88F5182 to Device Tree
This commit converts the RD-88F5182 platform to the Device Tree. All devices except the PCI are converted to the Device Tree. It is worth noting that: * The PCI description for the DT case is kept in board-rd88f5182.c. * The existing non-DT support in rd88f5182-setup.c is kept as is, in order to allow testing of a given platform in both DT and non-DT cases. It will ultimately be removed, once we no longer care about non-DT support for Orion5x.
