This commit migrates the mach-orion5x platforms to use the mvebu-mbus driver and therefore removes the Orion5x-specific addr-map code. The dove_init_early() function now initializes the mvebu-mbus driver by calling mvebu_mbus_init(). We also convert a number of orion5x_setup_xyz_win() calls to the appropriate mvebu_mbus_add_window() calls, as each board was doing its own setup for the NOR window or other devices. Ultimately, those devices will be probed from the DT. The common address decoding windows are now registered in the orion5x_setup_wins() function. It is worth noting that the four PCIe address decoding windows will ultimately no longer have to be registered here: it will be done automatically by the PCIe driver once Dove has been migrated to use the upcoming mvebu PCIe driver.
