arm: mach-dove: convert to use mvebu-mbus driver
This commit migrates the mach-dove platforms to use the mvebu-mbus driver and therefore removes the Dove-specific addr-map code. The dove_init_early() function now initializes the mvebu-mbus driver by calling mvebu_mbus_init(). The address decoding windows are now registered in the dove_setup_cpu_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.
