Harmony can be booted using device tree with equal functionality as when booted using a board file. Remove as much of the board file as is possible, since it's no longer needed. Two special-cases are still left in board-dt-tegra20.c, since the Tegra PCIe driver doesn't support device tree yet, and the Harmony .dts file doesn't yet describe regulators which are needed for PCIe. This logic is now enabled unconditionally rather than via CONFIG_MACH_HARMONY. While this is more code than other boards, it's still unlikely to be much of a problem, and both regulators and PCIe should be supported via device tree in the near future, allowing the remaining code to be removed.
